I love how everyone seems to forget that the ball is resting on some nails. It's not floating in mid-ai... in mid-vacuum. So even if it didn't radiate heat, it would eventually reach equilibrium through conduction. I do believe the radiative heat transfer is faster in this specific case than the conductive heat transfer. Like _way_ faster. But it's not negligible long-term.
Reduced to the actual cause of the 'heat' - which is insanely intense motion of the particles (the constituent parts of the atoms) of the metal ball -- -- all you have to do to answer the question "how will the metal ball lose its heat?" So another way to ask the same question is "what will gradually slow the motions (aka the kinetic energy) of the particles in the metal ball?" 1) the ball is 'transmitting' electromagnetic waves - and each electromagnetic wave the ball produces carries off energy from the moving particles in the ball. The electromagnetic waves that the ball is 'transmitting' are in the infrared and the visible light frequency ranges 2) the ball is held by a mounting 'seat' on a wood platform. As the ball's particles move around, they are in physical contact with the particles that make up the mounting seat. The motion of the ball's particles transfer motion to the particles of the mount. ANSWER: to prevent the ball from losing 'heat' (aka intense motion of its particles) - you'd have to somehow stop its electromagnetic 'transmissions' and somehow cause it to 'float' and not touch anything.

Yeah, that’s a pretty poor representation of a human hand vs red hot metal imo. Speaking as someone who has worked with 2000+F furnaces and has been burnt many times over the years. If it's hot enough, it will cut through flesh like a hot knife through butter. Especially skin, it's instantly gone. I have a nasty, thick scar on my upper arm from when I accidentally bumped into a ceramic plate that had just come out of the furnace. The furnaces typically have coolers on them that use liquid nitrogen like a cars radiator, except instead of coolant pumping through the system it's liquid nitrogen. But the cooler wasn't functioning correctly that day so everything coming out was extremely hot, actually 2000F is kinda on the lower end of the temperature we use in our furnaces, some of them get much hotter, although I don't know exactly how hot since I don't work on those myself. I only made contact with that ceramic plate for an instant and it cut right down to fatty tissue. Even if the coolers are working properly, anything coming out of the furnace is still hot enough to give you third degree burns for at least a few minutes. I have seen situations where furnaces were emptied with no cooling whatsoever, and being even within 15 feet of the exit of that furnace would have you dripping with sweat.
@@Lucius_Chiaraviglio it goes through several cooling zones with the last one being the most significant reduction. Yes, it can cause cracking if it’s not done correctly. The parts sit on a belt that moves very slowly, so it’s not a rapid process.

I mean, when we do the induction heat treat operation we use electricity to heat up coils red hot and basically instantly heat treat a part then immediately quench the part with coolant. I’ve never seen cracking being an issue with induction heat treat. Actually incorrect mixture in the furnaces atmosphere causes the most significant defects (Assuming temperatures are correct).

And the NSA is like: "Why do you want to learn about vacuum and hot balls? 🤨 You're trying to vandalize the universe, aren't you ?! ... Yeah, you got busted! 😏"
I have never grasped the three methods of heat transfer more clearly than in this moment. Even though you barely used any words, the descriptions made the most sense of any explanation I have heard.
To verify results, you should also check how long a red hot nickle ball takes to cool down in normal atmosphere. An any difference would prove that heat is propelled via light.
no, it already proves that heat is transferred via radiation. with your mechanism, any difference would prove that heat is transferred via air touching the ball.
It'll stop because the tension on the string is acting upon it to bring it to a stop. But while it's in the vacuum chamber, it would be difficult to hear
It's nice to remember that these vacuum machines can't even remotely reach full vacuum, the power is very small, there are many experiments that you can't do with them. An old mercury-based vacuum chamber would be needed, and yet it still has mercury vapors. So this experiment unfortunately failed in the question because there is still a lot of material to do the heat dissipation.
The reason the ball was able to cool down is the same reason the sun is able to heat up planets and other celestial bodies through the vacuum of space. This experiment successfully demonstrates radiation.
@@99mage99 The formula for heat loss by radiation is known, and it is much slower than heat loss by contact. Scientifically there really is nothing to say, it would eventually lose heat through radiation. But this was not demonstrated by the experiment, where heat was still lost through contact and not only through radiation. The concept pointed out by him is valid, the experiment is flawed.
(This reply is from before Headphone Legends edited the comment) No they’re not! The DEEP Web is stuff like servers and things of that nature. The DARK Web is the black market’s internet!
Not most effectively. Radiation is the slowest form of heat transfer for a given temperature difference. However it is the longest ranged method, and the one that works well throughout 99.999999999999% of the universe
Good video! A great thing to illustrate radiating heat would be a thermal imaging camera, or an IR temp gun, as they show you temps the object is radiating.

This is a good example of heat insulation. As there are much less particles of gas in the vacuum chamber, less gas particles will be colliding with the hot particles in the nickel ball. Meaning there is not much to conduct heat from he ball
So, what you wanted was a reminder that, to no one's surprise, heat can move through a vacuum, thus proving that the sun is not actually a lie created by the Illuminati? The pointlessness of this video is staggering to me...

When the bombs blew up over Japan, powerful radiation from the blast propagated at the speed of light, meaning if you had a line of sight to the explosion, you were instantly affected, well before the shock wave or explosion materials hit.
@@THEDnARACER yeah, I could have picked something cheerier. How about, "That's why when you sit around a campfire, you're better off sitting upwind from it. The wind blows the smoke away from you, and the radiating heat isn't affected by air currents anyway."
Sir if you are not a science teacher I wish you would consider it as today's youth really need someone like you who's love and passion for science comes through their work like yours does.
I remember when I was in high school, and had my fingerprints burned off... I was in welding, and someone didn't properly take care of a piece of 1/2" scrap that they welded. I guess they finished with it just before class was over, and during cleanup, I saw it on the table next to the scrap bin. Went to pick it up (stupid me without gloves) to toss it into the scrap bin, and it came up not even an inch off of the table, before sliding out of my fingertips. The way the ball reacted when placed on the silicone hand just reminded me of that.
@@ThePrufessa No idea how hot it was. It wasn't glowing anymore, but was still hot enough for it to just slide out of my fingertips. It wasn't a severe enough burn that my fingerprints didn't come back. They eventually did, but were smooth for a while after it happened.
@@ThePrufessa welding makes metal red hot. So assuming its AT LEAST 150+ °C My dad has vissible scars from small bits of molten metal. 70+ °C can already cause burn scars on human skin. I have a 1 by 1 inch but on my left wrist from 3 weeks ago when i had a small accident with 400°C hot metal. So burning your finger prints off. Probably between 150 and 250°C If the metal wasn't glowing any ore it cud be still about 100°C i guess.
It would be very interesting to have another ball with the same initial temperature outside the vacuum chamber to notice the difference on the coiling time,
What if the vacuum chamber had mirrors in it? Would that reflect the radiant heat back to the ball? Also a comparison with no chamber would have been nice.
Cool experiment. Something to try if you do this again. Use magnetic levitation for the ball so it doesn't conduct through the nail. Also cover the box with a mirror to reflect back any heat.
The ball can't be magnetised at high temperature, and some kind of electrically induced magnetism would be very difficult to set up. Perhaps possible, but technically very challenging.
*General Rule:* Don't use the word _absolute_ when talking about physical phenomena. It is not possible to achieve a 100% vacuum. Even for "only" 99.9%, it requires special techniques and equipment. Technically speaking, even the "vacuum" of (a non-trivial area of) deep space is not absolute.
@@wilFluffball it’s a closed container that seals up and has a vacuum hose attached to part of it to draw out the air from the sealed / topped container. Although I feel like while it is at a vacuumed state, there’s still the vacuum itself pulling the air (and potentially) heat out…
@@CanadaBud23 then might I ask how does he get it to full vacuum to begin with? 🤔 at least for a short time, that air has to get pulled out somehow Edit: that’s what I was meaning by the pulling, not the vacuum itself, but the obtaining of said vacuum
@@MysteryBatz You're not ever pulling a vacuum, that's a figure of speech. Pumps "push" the atmosphere out. The air trying to get in is the outside atmosphere pushing its way back in.

@@ZeusEBoy There are few hydrogen atoms per cubic metre in space. And we know photons carry energy aka heat. So are you trying to say, that rather then photons, we get heat energy by hydrogen atoms?

Hey man I love your video's I got 1 question that I have beet thinking about for the last few days: Why does a room with a temperature of lets say 20°C feel warm to your body (37°C) it doesn't make any sense to me, it would be much more logical if everything under 37° felt cold to your body, and everything above warm? (Maybe a stupid question😂)
Actually is a good question. I think it might be that we actually sense the rate of heat transfer as opposed to actual temperature. So if you touch metal it's colder than wood at the same temperature, but the metal conducts better and so transfers the heat from your body faster. Maybe....
37C will feel hot, because you produce heat and you have to get rid of it so you don't overheat. As you produce a lot of heat, the temperature to not overheat is roughly around 20C with clothes on. While there are a lot of factors involved, it basically explains the principle. Clothes do a lot here, so 20C naked will not feel warm over time, unless you are used to much colder temperatures (because your body can adjust heat production to a certain extent. That's why you see more people in spring wearing t-shirt than at the same temperature in fall) There is also some kind of adjustment that you don't really notice, when you sweat so little that it can evaporate quickly, so it doesn't build up. Does that answer your question? Edit: oh, and you will produce heat as long as you live, because biochemical reactions that make your body work are exothermic. The reaction (plus the friction between the cells) that "feeds" your muscles (turning sugar into co2 and water) for example is a strongly exothermic reaction. That's why the same temperature feels even warmer during exercise. (And your body utilises that when you are cold by shivering)
It depends on rate of heat loss from your body,if the loss is high, it feels cold, if the heat loss is low it feels warm, if you are gaining heat, it feels hot. That's why 30 degree water feels cold but 30 degree air feels comfortable.
Your nervous system doesn't even feels pain, feels like a little freezing ball but yea, stains looks similar and bubbling later. Im wondering if you will install perfect mirrors in the vacuum so it will recover the power lost on photon emmission. I think it will cool down slower
Is it possible to remove the magnetism by using counter magnets, perhaps to reduce its heat output entirely? Or compare that with air, no air, and magnets? I don't know, but this made me very curious.
Wrong reason. The death of the Sun, at least in terms that most people would think of it, would be due to the lack of hydrogen plasma in the core to fuse, making it shrink, but this makes the hydrogen outside the core start to fuse, which rapidly and massively expands the Sun to about a diameter of 2 AU, or roughly the diameter of the Earth's orbit, give or take a few tens of millions of kilometres. Once the hydrogen in that has exhausted itself, the Sun will shrink to a subgiant, roughly twice the current diameter, but after some time of this building up the pressure, the helium in the core will be of such pressure and density that it can actually fuse, and so it will expand the Sun again. But helium fusion is very unstable and combined with having lost gas from the weaker gravity of the red giant phase, the Sun will be rapidly losing mass. By the time the helium is exhausted, the Sun will have lost it's outer layers, but the now carbon core can't fuse, as it needs too much pressure and heat to do so, so the Sun's energy source will evaporate, producing a white dwarf, roughly a third to half the Sun's mass in an volume approximately that of the Earth. Considering that the full Sun has the mass necessary to pull on objects and keep them in orbit up to about a light year, or 12 trillion kilometres, away from the Sun, and has 99.8% of the mass of the Solar System with about 80% of what is left comprising of Jupiter and Saturn, squeezing even a third of that mass into the Earth's size with about 1/110th of the diameter, that should give you some perspective on just how dense that is. This is the thing that will radiate it's energy out, especially in the form of X rays, over billions of years, and eventually, that stops as the Sun approaches a temperature equal to the rest of the solar system, and so will become a black dwarf, when the Sun will really, really be dead.
Nah, probably 2.7 Kelvin, or however the physics would work out. The microwave radiation all around would probably keep you from dropping too low in temperature

I have never grasped the three methods of heat transfer more clearly than in this moment. Even though you barely used any words, the descriptions made the most sense of any explanation I have heard.
To verify results, you should also check how long a red hot nickle ball takes to cool down in normal atmosphere. An any difference would prove that heat is propelled via light.

no, it already proves that heat is transferred via radiation. with your mechanism, any difference would prove that heat is transferred via air touching the ball.
Try any object that vibrates (guitar string, a cymbal, etc etc) and put it in a vacuum chamber and see if it will stop vibrating.
It will
so vibrations dont go through our galaxy
It will stop
It'll stop because the tension on the string is acting upon it to bring it to a stop. But while it's in the vacuum chamber, it would be difficult to hear

It's nice to remember that these vacuum machines can't even remotely reach full vacuum, the power is very small, there are many experiments that you can't do with them. An old mercury-based vacuum chamber would be needed, and yet it still has mercury vapors. So this experiment unfortunately failed in the question because there is still a lot of material to do the heat dissipation.
There are other methods to gererate a good vacuum then mercury based pumps. But the one in the video was clearly not sufficient to go below 20 mbar.
The reason the ball was able to cool down is the same reason the sun is able to heat up planets and other celestial bodies through the vacuum of space. This experiment successfully demonstrates radiation.
@@99mage99 The formula for heat loss by radiation is known, and it is much slower than heat loss by contact. Scientifically there really is nothing to say, it would eventually lose heat through radiation. But this was not demonstrated by the experiment, where heat was still lost through contact and not only through radiation. The concept pointed out by him is valid, the experiment is flawed.

I feel it's worth pointing out that heat is most effectively dissipated in the form of infrared light, which would not be affected by a vacuum
Most effectively?
Idk about that chief, I get way more burned by touching red hot steel than I do from standing next to it.
Not most effectively. Radiation is the slowest form of heat transfer for a given temperature difference. However it is the longest ranged method, and the one that works well throughout 99.999999999999% of the universe

This is a good example of heat insulation. As there are much less particles of gas in the vacuum chamber, less gas particles will be colliding with the hot particles in the nickel ball. Meaning there is not much to conduct heat from he ball

I remember when I was in high school, and had my fingerprints burned off... I was in welding, and someone didn't properly take care of a piece of 1/2" scrap that they welded. I guess they finished with it just before class was over, and during cleanup, I saw it on the table next to the scrap bin. Went to pick it up (stupid me without gloves) to toss it into the scrap bin, and it came up not even an inch off of the table, before sliding out of my fingertips. The way the ball reacted when placed on the silicone hand just reminded me of that.
Damn. Wow. Any estimate of how hot it was? That's crazy!

@@ThePrufessa No idea how hot it was. It wasn't glowing anymore, but was still hot enough for it to just slide out of my fingertips. It wasn't a severe enough burn that my fingerprints didn't come back. They eventually did, but were smooth for a while after it happened.

Cairn heat is lost through radiation and not through convection and conduction as radiation do not need a medium to transfer heat
it is the comment that i am looking for.
What if the vacuum chamber had mirrors in it? Would that reflect the radiant heat back to the ball? Also a comparison with no chamber would have been nice.
Cool experiment. Something to try if you do this again. Use magnetic levitation for the ball so it doesn't conduct through the nail. Also cover the box with a mirror to reflect back any heat.
Also, aim a some kind of temperature sensor at it. It would be obvious it’s losing heat but where would be interesting.
The ball can't be magnetised at high temperature, and some kind of electrically induced magnetism would be very difficult to set up. Perhaps possible, but technically very challenging.
I burnt my hand pretty bad before and that demonstration just sent shivers up my spine
*General Rule:* Don't use the word _absolute_ when talking about physical phenomena.
It is not possible to achieve a 100% vacuum. Even for "only" 99.9%, it requires special techniques and equipment.
Technically speaking, even the "vacuum" of (a non-trivial area of) deep space is not absolute.
How did he remove the air from inside the box? I would assume an open container does allow air to go inside of it.
@@wilFluffball it’s a closed container that seals up and has a vacuum hose attached to part of it to draw out the air from the sealed / topped container. Although I feel like while it is at a vacuumed state, there’s still the vacuum itself pulling the air (and potentially) heat out…
@@MysteryBatz Vacuums don't pull/suck.
@@CanadaBud23 then might I ask how does he get it to full vacuum to begin with? 🤔 at least for a short time, that air has to get pulled out somehow
Edit: that’s what I was meaning by the pulling, not the vacuum itself, but the obtaining of said vacuum
@@MysteryBatz You're not ever pulling a vacuum, that's a figure of speech. Pumps "push" the atmosphere out. The air trying to get in is the outside atmosphere pushing its way back in.
I think you're underestimating the heat sink properties of the stand its sitting on. Would you be able to magnetically levitate the ball and redo the experiment? That would be AWESOME.

It will give away its heat by radiation and solidify
It's actually MOLTEN metal, not "melted"
It would de-gas then solidify, possibly at the same time if the metal has the proper melting point. Would be cool to see how different alloys react
I think you are hoping it will become foggy like water does in space. But you have to understand here it will not be free from gravitational pull so it will just rest at the bottom of the chamber
Depends on the metal. Molten mercury and molten tungsten will have vastly different results.

Hey man I love your video's
I got 1 question that I have beet thinking about for the last few days:
Why does a room with a temperature of lets say 20°C feel warm to your body (37°C) it doesn't make any sense to me, it would be much more logical if everything under 37° felt cold to your body, and everything above warm?
(Maybe a stupid question😂)
Actually is a good question. I think it might be that we actually sense the rate of heat transfer as opposed to actual temperature. So if you touch metal it's colder than wood at the same temperature, but the metal conducts better and so transfers the heat from your body faster. Maybe....
37C will feel hot, because you produce heat and you have to get rid of it so you don't overheat. As you produce a lot of heat, the temperature to not overheat is roughly around 20C with clothes on. While there are a lot of factors involved, it basically explains the principle.
Clothes do a lot here, so 20C naked will not feel warm over time, unless you are used to much colder temperatures (because your body can adjust heat production to a certain extent. That's why you see more people in spring wearing t-shirt than at the same temperature in fall)
There is also some kind of adjustment that you don't really notice, when you sweat so little that it can evaporate quickly, so it doesn't build up.
Does that answer your question?
Edit: oh, and you will produce heat as long as you live, because biochemical reactions that make your body work are exothermic. The reaction (plus the friction between the cells) that "feeds" your muscles (turning sugar into co2 and water) for example is a strongly exothermic reaction. That's why the same temperature feels even warmer during exercise. (And your body utilises that when you are cold by shivering)
Stupid question? no. But very amature. Im hoping you are 10yrs old
@@shahrukhs1637 actually it's a good question. The only irritation is your 'know it all' attitude. I hope you're only 9 years old.
It depends on rate of heat loss from your body,if the loss is high, it feels cold, if the heat loss is low it feels warm, if you are gaining heat, it feels hot.
That's why 30 degree water feels cold but 30 degree air feels comfortable.

That's our Sun... Eventually it will die
Wrong reason. The death of the Sun, at least in terms that most people would think of it, would be due to the lack of hydrogen plasma in the core to fuse, making it shrink, but this makes the hydrogen outside the core start to fuse, which rapidly and massively expands the Sun to about a diameter of 2 AU, or roughly the diameter of the Earth's orbit, give or take a few tens of millions of kilometres. Once the hydrogen in that has exhausted itself, the Sun will shrink to a subgiant, roughly twice the current diameter, but after some time of this building up the pressure, the helium in the core will be of such pressure and density that it can actually fuse, and so it will expand the Sun again. But helium fusion is very unstable and combined with having lost gas from the weaker gravity of the red giant phase, the Sun will be rapidly losing mass. By the time the helium is exhausted, the Sun will have lost it's outer layers, but the now carbon core can't fuse, as it needs too much pressure and heat to do so, so the Sun's energy source will evaporate, producing a white dwarf, roughly a third to half the Sun's mass in an volume approximately that of the Earth.
Considering that the full Sun has the mass necessary to pull on objects and keep them in orbit up to about a light year, or 12 trillion kilometres, away from the Sun, and has 99.8% of the mass of the Solar System with about 80% of what is left comprising of Jupiter and Saturn, squeezing even a third of that mass into the Earth's size with about 1/110th of the diameter, that should give you some perspective on just how dense that is.
This is the thing that will radiate it's energy out, especially in the form of X rays, over billions of years, and eventually, that stops as the Sun approaches a temperature equal to the rest of the solar system, and so will become a black dwarf, when the Sun will really, really be dead.
