Heat= Excited Particles= High Velocity Cold= Depressed Particles= Low Velocity Energy from excited particles pass to the depressed particles. Since the total amount of energy can not increase spontaneously, the energy becomes divided? So the depressed particles speed up the same amount that the excited particles slow down until they all carry equal energy?
I have a question, in the beginning, you mentioned that heat is not seen to flow from cold to hot, maybe you might refer to net heat transfer? I just have a thought that more heat flows from hot to cold than cold to hot, but none of the values be 0
What do you call "ordered"? If you have a finite number of states, as you can always consider, then the power set is equivalent to the natural set. Now divide the power set in two sets, the one labeled with odd numbers, and the one labeled with even numbers. Those sets are equivalent. If one of them is labeled "ordered" and the other one "disordered", then order and disorder happens with the same probability. I think the right way to state it is: under certain conditions (natural spontaneous conditions) some configurations are favored over others. We happen to observe the favored ( disordered ) more frequently ... and that is because of the limitation of our methods of observation that disturb the conditions ...
I also saw the video about gibbs free energy and spontaneity from khanacademy where the speaker was very good in explaining it, he spoke slowly and throughly explained stuff. You are speaking so fast and there are so any macro and micro states that you are just confusing people. I think you need paraphrase things properly, slowly and in order. No wonder this video has less views, Khan academy, thank you for all the great videos.
This law needs to be reevaluated by the scientific community because it doesn't make sense for the two same constituents of the system not to exert equal forces on one another. When something acts upon something, there's always an equal force back in reverse!
I think its because the molecules in a hot substance are already moving faster and the ones in the ice cube which are almost still get overwhelmed by the power of higher energy fields. Because energy is shared between the two states the one with a higher frequency of vibration is going to be moving with much more energy and literally overwhelming the cold ones. In a glass of water with an ice cube, the water "gives" its heat. Like a crowd of people running is going to overwhelm a small group of people and make them run. Higher frequency and in higher numbers means higher energy and more overwhelming power. Just like an atom bomb, more atoms, more reactions, more megatons , more energy dispersion, more destruction. So basically if you put an ice cube in water, the ice cube appears to drain heat energy from the water, but thats just the higher numbers in both energy and frequency invading the spaces in the ice cube because the energy is confined and compacted in the limited space of the glass. And if you drop a tiny bit of water on a big chunk of ice, the water will eventually freeze as it runs out of energy. There are 4 Forces in physics, strong nuclear force, weak nuclear force, electro magnetic and gravity, but theres also dark energy and dark matter and theres also two other Forces yet to be discovered. Lets call them planks, planks are hypothetical, they are the smallest particles in the universe and make up the very fabric of space. Imagine empty space has no empty space, its all filled with tiny planks, now imagine two types of planks, one attracts, the other repulses. Lets call them negative and positive planks. Now imagine these planks as the two extra Forces in the universe. Its because of them that we have physical matter, they are what makes up all the Forces in the universe, they make up the frequency that create strings, in string theory, and therefore make up all particles and therefore make up all molecules. Now this where science ends and science fiction begins. We can only hypothesize on this, but imagine these planks are connected and they obviously connect everything else. This is what they call the zero point energy field and what Einstein called space-time in his theory of relativity. Now if youre familiar with Bell's experiment on quantum entanglement, you could hypothesize that the basis of quantum entanglement communication is actually just interaction with the zero point energy field, which literally connects everything. So when we find a way to interact with planks we can communicate instantly between galaxies. And if Alcubierre's equation is right, we can also learn how to manipulate gravity by rearranging planks and contract and expand space. Just like Bob Lazar said, we could travel between solar systems instantly. Now we just need two things, a chemical element to generate a gravitational field around the space ship, thats a stabilized version of ununpentium or something else, element 115 as they call it. And a ship equiped with a reactor capable of generating the gravitational field around the space ship and also equiped with the means to generate a distortion around the ship. Basically it contracts space in front of the ship and expands it behind the ship, making it move forward without breaking any rules of thermodynamics, because the ship is inside a gravitational field, literally an indestructible force field and the laws of inertia do not apply to it. So this is how aliens travel. Lol, wtf did I just wrote?
Ok so this was to explain the reason the energy moves towards the cold is because of two things, first as I stated in my previous comment, the higher frequency overwhelms the weaker one, but the second reason is because planks, namely negative planks in the cold pull the positive planks in the hotter water. I just made that shit up.
Hello,I have a question, you said disorder will always increase, but when crystals are formed the order is increasing? Is this because this isn't a closed system?energy has to be inputted?
Johnny Law on your tail? Need to sue your neighbors? Trouble with a tiger? Whatever your legal quandary, you can bet Albuquerque’s resident criminal lawyer Saul Goodman has the solution. Better Call Saul Goodman :)
I have some difficulty with this one. For instance, if I hold a ice cube in my hand for few minutes then release the cube to place my cold hand on my arm. After few minute the place on my arm where I pressed my cold hand will have become colder than the rest of my body. I have transferred cold from the ice cube to my hand then to my arm the same way it would have transferred with an hot object.
Not exactly that. If you have an ice cube on your hand. Heat transfers from your body to the ice cube, melting the ice cube. But, at the same time, this also makes you hand slightly colder. Now that slightly colder part of the hand Is placed on your other part of the body and the same thing happens where heat is transferred from one part of your body to your hand. And now that other part becomes slightly colder. But, it warms up again because human body is constantly evolving heat due to various reactions.
@@Coconinga Ok. But if I use an object instead of my body and ice it does the same thing. Is the law only applicable to working devices since it was stipulated from vapor machinery observation?
you mentioned that energy from the cold object will not be transferred to the warmer object but when you drew up the disordered/mixed up diagram you drew the cold energy migrating all over the place. Did I misunderstand something? I thought the cold energy doesn't move.
Can you explain this? During winter, when I stick my tongue on a metal pole it gets stuck. The heat from my tongue flows into the pole. After some time, hypothermia sets in. But that is a different matter. Yet I feel a sharp painful cold before my body becomes numb. Isn't this "information" cold flowing back into the hotter object?
Well, hopefully someone already answered this for you in the couple of months since you asked. However, if not, the reason is that what we perceive as "hot" and "cold" is not a direct measurement of temperature, rather we experience *change* in temperature. So the sharp painful cold you felt was your body's way of letting you know you just lost a great deal of heat in a short period of time. Consequently this is why room temperature metals feel cold, they are good conductors of heat.
Great question, Im no where near qualified to answer your question legitimately, but my assumption is that the 2nd law still holds; since your tongue is significantly hotter than the metal pole, as soon as your tongue and pole come into contact, the heat from your tongue travels into the pole very rapidly and thus you feel painful cold from the rapid loss of heat. If you were to touch a surface that was only slightly colder than your tongue, not as much heat would transfer and thus you wouldn't feel that sharp pain
Technically speaking muscles like rubber are elastic in nature so it cools when contracted and heats up when stretched, (and the reverse is also true) The pain is due to the sudden contraction of muscles, caused by sudden loss of heat. If you gradually lower your temperature you'll just go numb, and won't feel that sharp pain. It's not information, it's just the mechanics of your body, reacting to external stimuli
But, The theory of very large set says that even the events with very less probability will occur given enough time.Since heat flows all around us isnt it possible that in one of the case the heat fliws from colder object to hotter objecy spontaneous
By the word itself "probability" does that mean its not possible? Even if probability is 1 to the greatest number you can find it must happen (1). We just dont know when but if their randomness puts into right condition it might be earlier than what we think.
I don't know if thos is right , but if the chance of the red balls and blue balls become ordered again isn't zero , so is there a chance of this system to become ordered again ? And if that happens the disorder of the system haven't decreased?
Umm... what does this have to do with "The entropy of an isolated system increases in an irreversible process and remains unchanged in a reversible process."?
When systems go from a seperated macro state to a mixed macrostate entropy increases because the amount of microstates that are possible increases. It happens because statistically, the balls from left and right will just move in a way that mixes them if there is no barrier.
Does it violate the definition of entropy change: dS = dQ/T? For the total system described in the video, dQ = 0 and dS should be zero. However the S increases.
Wait so if you put an icecube and a hot block of copper together the chance of the cube being hot and the coper being cold is the same as the cube just melting?
Gabriel Rodriguez This is one example. The second law of thermodynamics applies to almost every facet of life. In simple Terms, things such as gases dissipate or fall out of order. Physical things break apart. Things fall away from each other. And example of this is say an iron ball. An iron ball will remain intact for a while. From an observational standpoint, it may seem the same but on a microscopic view, the molecules are breaking apart. In time that ball would disintegrate. Things fall apart or separate. Nothing is kept in order. A tree grows sprouts but with time it gets old breaks apart.
Yes. Technically, you are correct. There is a mathematically non-zero probability that an isolated system can evolve into a highly ordered state with lower entropy. However, as the size of the system increases, this probability rapidly and exponentially decreases, such that for systems of macroscopic size (millions, billions, trillions, trillion of trillions of atoms) these probabilities are so astonishingly low that for all practical purposes the second law of thermodynamics becomes a "law" in much the same sense as the first law of thermodynamics (conservation of energy). I once read a thermal physics textbook which had a fantastic quote: "[thermodynamics] works because Avogadro's number is much closer to infinity than it is to 10". That's true in a statistical sense, because many theorems which derive from the second law are dependent on formulas which only become absolutely true in the limit of a large system size. It just so happens that atoms are so small that pretty much any system large enough to see with a human eye will obey these laws without exception.
I always thought it was entropy of an isolated system that is greater or equal to 0 (not a closed system which can exchange heat but not matter with surroundings)
what about an object cooled to absolute zero, the molecules would stop and the speed of light would decrease, at this point the second law of thermodynamics would be redundant and the energy movement would then only be observable as sub atomic particles, which would then be able to operate outside the bounds of the second law of thermodynamics.
Maybe it is possible to work out such things, our technology might not be able to directly tackle these questions but certainly could be used for indirect study
I have a question. Once the entire system has achieved a steady temperature, would that mean that it would now be an ordered system? since every circle is red in the system. Do you know what i mean? lol
Refrigerator isnt forcing cold into hot. The evaporator is absorbing heat energy from the air volume in the refrigerator. As the air temp drops below that of the food heat is transferred from the food into the air where it is used to facilitate the evaporation of the refrigerant material. Therefore it is still in compliance with the 2nd law. (I'm a self educated hvacr tech)
The last equation and remark, together seam weird to me. The equation seams constant. Whereas he says Entropy rises. K is a constant, W is a constant.. what changes?
+Jonathan Somer It's because of the logarithm function. If we take the limit as W approaches infinity, the entropy will also increase to infinity :) . Also W is not a constant
5:30 discussing the probability of all the balls being separated by color. Yes there is less probability of that 1 state vs the probability of all other states combined. That's basic math. But there should be the same probability for each individual state to exist therefore it is as likely that they will segregate by color as any other single state.
Move heat from a cold object to a hot object using a refrigerator or heay-pump??.....a refrigerator of the vapour compression type has an evaporator containing a saturated refrigerant or 2 phase mix, which is at a lower temperature than the product!!....hence the transfer of heat energy!!......this is not 'cold to hot'.....I will stand corrected should anyone wish to point to my error!
+Robin Francis You left out or misunderstood the word "spontaneously". Refrigerators and heat pumps do work to change the system and surroundings, thus the heat transfer that takes place is not spontaneous.
In a closed system, i.e. "spontaneously", in a system where there is no force of outside energy. If the fridge wasn't turned on, hot food put inside would heat the fridge. When the fridge is plugged in, there is outside energy forcing the cooling of that food. Evolution is not a closed system there fore has no bearing on the overall state of order. All this is I learned from the video!!
This video doesn't help me at all hahahaha. I would rather try to understand the equation and finish my college with B grade than suffer at this silly explanation.
This law is stupid, it’s too obvious to be a law. If you tell me that it’s a good way to look at things, that’s fine, but make it a law, that sounds ridiculous to my ears
The way sal kahn and his team describes is just loving!
Heat= Excited Particles= High Velocity
Cold= Depressed Particles= Low Velocity
Energy from excited particles pass to the depressed particles. Since the total amount of energy can not increase spontaneously, the energy becomes divided? So the depressed particles speed up the same amount that the excited particles slow down until they all carry equal energy?
I love this 😂
Very well I've covered the second law of thermodynamics.

he sounds a bit like mr poopybutthole. But sick vid man! Very very useful
I don't understand the statement 'the first law of thermo doesn't account for the direction of spontaneous processes.' I don't see why not.
The order state describes an ordered universe so there is a disorder cause you describe a closed state
A disordered state describes a messy room
So your disordered state is not physics
what about an object cooled to absolute zero, the molecules would stop and the speed of light would decrease, at this point the second law of thermodynamics would be redundant and the energy movement would then only be observable as sub atomic particles, which would then be able to operate outside the bounds of the second law of thermodynamics.

When the fridge is plugged in, there is outside energy forcing the cooling of that food. Evolution is not a closed system there fore has no bearing on the overall state of order.
