Don't make this mistake! When a liquid evaporates or boils to become a gas, the molecules DON'T come apart! This is true whether you're talking about evaporation, boiling, or vaporization.

I wish i could get a chemistry teacher like u early .. i just wanna thank you from my heart ...and god bless u ,, may u live long 100 years more
BORON BARUAH you must be a nice guy
Hey everyone, I'm here to help. If you have any questions or just want to learn more, click on the link in the description above. It'll take you to a page where you can ask me questions.
I started loving chemistry since ever I got chemistry videos!!!!
Thanks alot
I like how you explained it very visually and clearly. ..H2O looks like Mickey Mouse :)
leah km
Hahahahahha i love what you said lol
Thank you so much. I was explaining this exact thing to some curious kids but told them the wrong one... now I can go correct my mistakes. But seriously, I've been looking on TH-cam for at least an hour and you are the first person that explains this... at least clearly for us not so smart folk.
its great how you are so enthusiastic about chemistry!
May god always be with you in every step you take !
This is really well done. I just imagine what you would be able to do today.
This guy deserves over 1mil subscribers.
THANK YOU so much sir!!!
Awesome video! I love the sound effects of the molecules of water shooting out into the air. And the Big Red X to indicate NO to that description ;D
Bundle of thanks for giving such a huge inforamtion
thanks for clearing that up!
Great demonstration of change in physical properties. Our book used water molecules as an example but I did not pick up on it applying to other molecules. Thank you for the clarification.
Its been 9 years :> and I'm watching this now ;)
Loved the way you teach us
Thanks a lot. May you have a long life of health and happiness.
Thank you! I will be studying chemistry next year and these tutorials really help! I know right, about the gasoline thing? It smells so good!
sir i need help in electronic configuration
Thanks for the info. It's very helpful with the school project.
"This is wrong!! Here's the big red X." Hahahaha... LOL!!!! Yes I love it!!!! :D
Thanks for the info. It's very helpful with the school project.😀
Thank you very much.Your lessons are always very easy to understand and this was too.....
your presentation is very nice
Thanks for help
Could u please make a video for vapor pressure
Can you make a video on equilibrium constant and how to use the "ICE Table"?
I'm about to take basic chemistry so i'll be sticking around for a while.
thanks, your video helps me a lot :)
can you please upload a video on crystals?
would it be correct to say, that the molecules dont split apart, but the heat turns, one drop of water, into a bunch of little ones? which are now able to fly, being so small? what would pressure do in this equation? im always reading about the Dissociation of salt (sodium chloride) in water creating sodium chloride solution. But it doesnt make much sense, because I cant see how it would do that in our body, which is under pressure. Because salt helps our blood retain the water, and we are still able to send eletrical signals from our brain, which runs on about 5 volts? why is pressure never a factor in these rules of chemistry? which i know nothing about, but im just good at recognizing patterns that dont match up. Hope these questions arent too rediculous. Its how I learn.
Great video. Thanks.
Could you explain how water molecules manage to expand some 1400 times itself when boiled and still hold its structure as a gas?
Can you please explain why water freezes in a pressure chamber? For example water starts to boil at a much lower temperature under lower atmospheric pressure, yet it still leaves frozen ice?? Just a little confusing to me.
Also, when water is boiled in a pressure chamber does the atmospheric pressure become higher due to the water turning from a liquid to a gas?
thanks for the help
Fabulous explanation
how about giant covalent compound when they melt?
Wow.. i just checked and you made this channel even before i was born..
Good info..
nice way to explain
What is the difference between evaporation and boiling?
when water,i.e, H2O evaporates, it is gas waterand it's still H2O in the gas. the composition of the atoms in the water molecule (H2O) does'nt change but how come the state or the form changes??(into a gas). can you help, sir?
So much Engagement!! U r the besttttt!
Awesome!
What is gas constant
When you boil something, it evaporates?
@Tyler DeWitt how does water manage to evaporate below its boiling point?
Change in pressure
Some of the molecules just happen to have enough kinetic energy even when the liquid is far below the boiling point. Temperature is related to the average kinetic energy. Just as some people are much taller than average, some molecules happen to move much faster than average. The fastest molecules that are near the surface of the liquid evaporate, so a puddle slowly disappears.
Loved it!
Does iron evaporate?
Some compounds do decompose before they hit the boiling point though.
True and a good point. However, in such instances it would be inappropriate to use the words "evaporation", "boiling" or anything similar. Instead, you would just say "Add energy until the substance decomposes."
Evaporation n Vaporization are not processes involving CHEMICAL change but only PHYSICAL change
Decomposition is completely Different topic bro
very good
Is evaporation and boiling are same thing
It would be easier to say that when water (or any other substance) evaporates, it continues to be water, so the molecules of water maintain their identity and they don't break apart. If they did, they wouldn't be *water* anymore, but oxygen and hydrogen. Similarly, if gasoline molecules were breaking apart during evaporation, they wouldn't be gasoline anymore, but some other simpler substances, such as methane, ethane, carbon dioxide etc. And if they break apart too into single atoms, there would be no gasoline anymore, but gas carbon and gas hydrogen.
But I wonder... how does it apply to ionic compounds?
From what I observed so far, most ionic compounds are solid in room temperature, and they don't melt easily to become liquid, not to mention boiling to evaporate. But I don't know _all_ ionic compounds out there, so perhaps there might be such which are liquid or which can evaporate. So what about them? What happens when they evaporate? Do their atoms (ions) break apart or not?
Perfect. Where can I find more video from tyler dewitt?
youtube duh
@@rainsmush what do you mean? What is TH-cam duh
Wow..thats awesome
You're a Chemistry God! I'm your biggest fan huhu!
thank you so much...
Thanks bro👍
best explanation.
So why doesn't water boil when it evaporates? Like if you leave a bowl of water outside on a hot day, the water will all eventually evaporate, but it never seems to boil. How does this work if the way it turns to gas is by heating up so much that the molecules get a high enough level of kinetic energy to become a gas?
Thank you
Mesmerizing
So when I'm sweating, the liquid sweat evaporates and cools me off. How does this work? I understand that water can transfer heat very effectively, but why
Water evaporates even at temperatures below 100 degrees of Celsius.
In the process, it takes away the heat of vaporization on your body. This is reason.
Water vapor can't transfer much heat on your body because of water vapor is a very small amount.
So main part of the cooling is the heat of vaporization.
For example, transfer heat of 1g water is like 4.2 J.
But heat of vaporization of 1g water is 2250 J.
The value is not absolutely correct, but it is approximately true.
My students like your explaining!
you are amazing like i watch a 5 min video of yours and get everything but i sit and listen to the teacher 120 min and i still don't get anything
Can you make a video on trends in melting and boiling points of elements 😁😁
Oh... Thanx for the video
Huge fan!!!
please explain how does evaporation causes cooling
Muhammed Sufiyan... Evaporation causes cooling... Take an example.. If we take some water on our hand and then just leave it.. What will happen..? The water take heat from our hands and evaporate... It takes heat from our hand... It means take heat from our body... As a result our body temperature decreases n we feel something cool in our hand
I know right he is awesome! :)
I love the smell of gasoline, and Tyler dear u just gave me another reason to love u!!!
I'm still confused as to why any liquid evaporates without reaching its boiling temperature. Is just heat energy causing the molecules to move more rapidly and drift into the air?
happens when heat is applied to the "surface" of a liquid causing the molecules @ the top to gain energy and move faster. The molecules at the surface stay there as they become less dense. No convection currents occur hence the more energetic molecules leave to go into gaseous state.
leaving of more energetic molecules cause cooling to the rest of the liquid to cool
super sir..
great video
thanks a mole sir :)
Lovely
yeah but when a liquid evaporate it doesnt need to boil, right?
Pressure changes can help
man this video was steamy...
Good
I love you!!
Great
how can a person be so handsome and intelligent at the same time ?!!
Hahaha, at least I'm not the only one who loves the smell of gasoline! This video made my day :')
Haha thats makes three..
Oh yah
Hope you like lung cancer lol
@@youraveragerobloxian3792 We're not sniffing it on purpose or anything! It's just that we like the smell.
Loving the taste of pop and drinking pop to excess are two different things.
yeah don't they just break the intermolecular bonds?
Yeah its true that liquid gasoline will not change when they bcome gas, but if there are combustion reaction, they will change,
Atoms of most elements and compounds doesn't have independent existence
only when you stick positive and negative volts under water.
Octane is not the only molecule in gasoline. Otherwise, solid game, son. Respect: from a fellow chem teacher.
Moreover, they fly up not only as molecules,but they fly up as small droplets too.
This confusion comes from not understanding INTERMOLECULAR FORCES
This topic is reponsible for
1. Phase changes and colligative properties
2. Surfactants
And many others. To be a seasoned Chemist or scientist, make sure you are well versed in that topic. It's the most easily confused topic.
🥂
I thought this guy was joking but it's baffling when looking at the comments that ppl do make these mistakes😦😦 and I thought I was dumb for not fully digesting Special Theory of Relativity smh
You do not know where these people are in their educational experience. Some of the people commenting may be very young or just didn't learn this topic fluently. You should not allude to others being dumb just because they don't know something that you do. Your comment is absolutely arrogant in nature.
Nicely explained, wish all of Chem was taught like this. Just one flaw, there was no explanation of vapor pressure formula. :(
my guys shirt about to rip cuz they too tight
I came here for Evap vs Boil.... But all i got was Evap/Boil vs Fission.
*BIGGEST MISTAKE IN CHEMISTY: BOILING IS EVAPORATION*
Why not explain partial pressure vs vapor pressure vs temp.... This is something *Most* people actually don't understand.
shellnut shellnut shellnut shellnut shellnut shellnut shellnut shellnut
We know that😣😣
But wouldn't it be nice if they did?
ZOOM!
I had no idea that there were people that like the smell of gasoline! I don't mind it, but I don't particularly like it.
Who the hell on this planet thinks like that ???
Sheraz Khan buhahahhahhaha :D
Same here dude, love the smell of gasoline
smell of gasoline totally rocks
People don’t seriously think water evaporates into oxygen and hydrogen…? It’s pretty obvious that’s not what steam is 😅
i also love the smell of gasoline
Was the separate front and hand view at the same time disorienting only for me?
