No jargon, no BS intro; cuts straight to the point with clear animation/demonstration and simple explanation. We need more such videos! Many thanks to the creator!

The only video on youtube that explains this concept perfectly!!!!

The world needs more simple videos like this one !

seriously! many many many thanks. You don't know how happy I am feeling after watching this video. It helped me solve my long pending answer. Had you been here...i would have kissed your hand sir. Thanks once again.

Simply brilliant...this is the clarity every kids taking science should have

By far the best explanation I've come across

this man's a legend! tomorrow's my exam and your video singlehandedly cleared my understanding of this topic and i have been struggling for weeks! Thank you so so much!

that's what every student needs.easy and simple explanation .

Wow. Such a perfectly explained video without being overly complicated. I loved the use of analogies and real life demonstrations. That was perfect.

This is a GREAT video and showed exactly what I wanted to understand! Thank you so much for taking the time to create and share this! Just a minor suggestion, and this only because I'm coming from the point of view of someone who does voice overs. There is a good deal of mouth noise in the video which can be mitigated by setting your microphone to cardioid mode, dropping the gain a little from what it was, making sure your teeth are brushed and having a cup of a hot, clear liquid such as apple cider or hot tea. Just throwing my 2 cents in from my experience. Again, the video was awesome and I have not yet found a better one! MUCH appreciated!

I think my favourite part about learning concepts is that click moment where you didn't quite understand something and then suddenly it all falls into place.

For a period of 6 minutes, I fell in love with physics. Nicely done explanation. Thanks,

This video is really helpful sir. Our teachers don't tell the concepts behind the facts but you have explained all things. I saw a lot of videos on KZfaq for vapour pressure and boiling but nobody explained so nicely like you. This 6 minute video really failed 1-2 hours lectures..... 😎😎 Thank u sir for making such helpful videos.

At 1:20 you say "only 50 kilometers has enough air for humans to breath." But 50 kilometers is approximately 31 miles; and 26,000 feet (8,000 meters or 4.9 miles) is the official ‘Death Zone’ where severe altitude sickness occurs without the use of supplemental oxygen. Other than this bit of confusion, the video is really good. The best explanation of boiling I've ever seen.

Kudos to the creator for making this concept clear to me...

1:56 my chem teachers piling chemistry on top of me

I am truly grateful to you. I never thought it would ever be so clear to me. Thank you very much.

Perfectly explained.I was having a doubt in this topics for a long time but you cleared it.Your explanation is brilliant

Amazing presentation! no crappy intro, music or anything, and the part of showing which topics are next. Thank you!

I don't even have to rewatch many times to understand. This is the best Explanation ever. Thank You!

Absolutely the best explanation of this here in youtube .Thank you so much Dr.Breslyn!

Finally , I got what actually boiling is.... Thanks a lot ... I had a misconception .

Generally I don't comments on any kind of videos but after watching this video I can stop myself to do this ... perfect concept

The most perfect video on youtube to understand boiling phenomenon and vapor pressure!

Wonderfully explained. Only Video on this topic with so much clarity. Seriously thankyou very much.

This is the most creative way to describe these things! thank you so much for this!

Hello Wayne Breslyn, before I tell you why I commented I want to tell you what I think the meaning of life is, the meaning of life is to know as much about the world around you so that you have the advantage over others to manipulate it (knowledge is power) At 2:05 when you explain why water powers at a lower temperature at higher altitudes I feel like I unlocked a piece of knowledge about the world. For me the whole reason I even care is because if I ever go camping high in the mountains with friends and I boil water I have the knowledge to explain why the water boils faster. I have the power to educate others because of you. Thank you. Some people take for granted that they live in the Information Age, in a time where you have access to learn about (almost) anything about our world and the universe.

Came here to try to understand the concept of Vapour pressure, nd I understood a lot more things than I was expecting, thanks so much.

Finally something that was confusing me a lot is clear Thxx✨

This is a really nice description of boiling and an important concept in human physiology and a great segway to understanding absolute and relative humidity... Have you ever thought of doing a video on those concepts?

You are really amazing teacher sir. I am in class 12th (india) but didn't know the real Concept but the way in which u explain is outstanding. Hat's off to u sir

before this i just know the definition of boiling but you changed the whole viewpoint superb sir

Super useful for my HVAC class that I’m taking. Thank you!

Thnku so much for this video ...it made my concept clear..

best explanation ive come across on boiling point

Finally a good one to understand this confusing concept🙌🙌

THANK YOU for explaining it completely! apparently some geniuses don't care to explain the effect of Atmospheric pressure on liquids, which made it frustrating to understand :/

Amazing video, loved it! Helped me understand vapour pressure in less than 10 mins.

Thank you soooo much for giving us a clear explanation. It's really helpful to understand about boiling point and pressure more clearly.

I feel there should be more said about what exactly it is and what causes it to go up and down.

Wow. Such a great simple explanation, but in depth too. Helps for AP chemistry. Forgot my honors chemistry

This video is fantastic! Thanks so much for it! I finally understand these concepts! You’re a lifesaver!

thanks a lot,everything explained that i had a doubt about.u earned a like.

Thankyou. Lots of love and respect🙏😊

Thank you. This has cleared up my confusion😊

thank you very very much. this video helped me so much and answered my long-time questions. I'm a mechanical engineer.

easy to understand in molecular level

This channel is a miracle undoubtedly 💙

What an excellent video!

Ohh myyy goshhh!!! This video is a life saviour 😲😲😲😲😲

How does water vapour form? Please make video on this topic.

Clear and conceptual explanation thank you sir 🙏🙏🙏🙏🔥🔥

No words guruji...I saw miracle...I saw a wonder....👏👏

Thanks about this information about boiling. It was so useful 😃😊👍🏻😄

This is GOLD!!

Best n simple for understanding 😊

Love how he explains it simplefor kids to understand

but why temperature becomes constant during boiling and doesn't increase further even on adding heat?? if its just the game of bubbles it doesn't the explain why the temperature can't rise further ,,,if I say that below 100 degrees the energetic water molecules forms bubbles but those bubbles don't have that much vapor pressure so it collapses but at 100 degrees they have enough vapor pressure to escape but even above 100 degrees the bubble have more pressure right? and more bubbles will form because there will be more no. of enough energetic molecules ....so why it doesn't rise above 100 degrees ?

I appreciate the video. Have a test tomorrow where I need to be able to explain this, but and this does a great job, I think my understanding on this topic got a lot better, I liked the visuals too.

he is best in this business!!

Wow brilliant 👏👏sir I under Crystal clear this topic

Thanks for the vid really elucidated everything

Thanks for such a nice explanation

Thanks for the video it helped me out a lot!

if water vapours are pushing against atmospheric air means they also push water down there, since pressure acts normally in all directions. How would this be correct explanation?

adv chem anyone?

Very well explained

I m so curious to know what is boiling point, and I get the feel of boiling point. I appreciate your efforts

**Video Summary**: As heat is added to water, water molecules gain energy and move faster, eventually forming a gas known as water vapor. This vapor is what constitutes the bubbles seen during boiling. The process starts with water molecules, where oxygen (red) and hydrogen (white) atoms combine. As heat is applied, water molecules move faster and can spread out, forming water vapor. The black areas represent empty space. Boiling involves the formation of bubbles due to the spreading out of water molecules in the form of water vapor. This spreading pushes surrounding molecules away and results in bubble formation, causing the bubbles to rise to the surface. Atmospheric pressure significantly impacts boiling. Earth's atmosphere creates pressure; the lower we go in the atmosphere, the more air molecules exist, leading to higher pressure. However, as we move higher in the atmosphere, fewer air molecules result in lower pressure. Atmospheric pressure arises from the mass of air above us, which gravity holds close to Earth. This downward pressure due to gravity prevents the atmosphere from drifting into space. Atmospheric pressure affects boiling. When we ascend a mountain, the decreased air pressure allows water to boil at a lower temperature than at sea level. Pressure variation impacts the behavior of water molecules and their ability to form bubbles. Boiling is determined by the interaction of atmospheric pressure and the vapor pressure of water molecules. Vapor pressure arises as water molecules escape the liquid and collide with air molecules. The atmospheric pressure pushes down on the liquid, making it difficult for bubbles to form. When vapor pressure increases, it counters some of this pressure, making it easier for water molecules to form bubbles. This balance between vapor pressure and atmospheric pressure defines the boiling point. Boiling can be induced by increasing vapor pressure or reducing atmospheric pressure. Once these pressures are equal, the boiling point is reached. Different substances have distinct vapor pressures due to varying molecular attractions in the liquid state. Stronger attractions result in lower vapor pressure, leading to higher boiling points.

Excelent video. Thanks

This is a great explanation!

Thank you so much! So easy to digest and understand. Really appreciate it

Thank you very much!!! great explanation

You have explained this sooooooooo well!!!!!!!!😮😮😮

This was a well done video. Thank you for taking the time to make it!

Thanks alot Such a nice explanation

Thank you so much, sir. I was wondering how bubbles are formed and what boiling is, and what's inside of the bubbles. You solve all my questions. Some folks say that the bubbles are made of some gases like CO2 that are dissolved in the water, when it gets heater, the gases will be forced out of the water, and release up into the air. Most of people believe except me, because I know it's not possible that water can absorb that amount much of gases and keeps releasing them out. And that's why I'm here, searching for the answers, and finally find out that they were wrong, all wrong. The bubbles are actually water vapor, which means they're still water just changed their forms. Thank you again for teaching me a new lesson! Hope your channel be more popular and keep teaching others. We have enough fools now.

does vapour pressure act only against the air molecules and not on the surface of liquid?

I was curious about that, it pretty cool.

Finally,find it. Absolutely great work. Thank you sir

Very simple, very clear and very good explain for understanding. Thanks 👍👏👏👏👌

Genius explanation

Beautifully explained

Increasing vapour pressure decreases atmospheric pressure but it can also increase the net pressure on liquid surface right how can we say that net pressure decreases just because atmospheric pressure is decreasing?

thankx for an amazing explanation. ..amazing help for class lecture~

how to form vapour pressure while the atmospheric pressure prevents bubbles to form ?. u said bubbles form the vapour

Why water and vapor temperature are same at boiling point.... Explain?? Merci beaucoup **

I’m a little confused. Certainly the amount of energy I have to give the molecules to break their hydrogen bonds isn’t dependent on the pressure of the atmosphere and yet it’s true that water boils quicker at lower pressures. What gives?

I loved the explanation! Tysm😊 U got a new subscriber 🤍

Best explanation sir :) Thank You

I am truly amazed that water molecules can expand when heated and separate a huge amount of air that can form an air bubble or is it water vapour ? When I look at a cold container of water there is clearly no visible trapped air . Then when heated there is an unlimited amount of ( air ) bubbles until it boils dry ? It looks like the best magic trick . ?

How does the boiling water choose which molecules to turn into vapor first. I do not believe it is random.

Sir does low atmospheric pressure decreases van Der wall force?

Isn't the vapour pressure some parameter in a closed vessel? And not an open one, pls explain... Btw best video on this topic on KZfaq!

Excellent!

Great video

I have a Liquid Oxygen container at -196C, as per heat transfer I calculated a vaporization daily rate of 0.1036% at ATM pressure. if I increase the container pressure to 0.1519 kg/cm2 how much will the vaporization rate decrease?? How can I calculate this? I'm kind of lost, I was trying to use this ecuation but then I think probably is not the right one for my problem.

Great video ❤😊

Correct me if I'm wrong, please ... But isn't water in its gas state called steam? Isn't water VAPOR what we call water that should be liquid but is in a gaseous state, like when it condenses into fog/clouds? I thought that steam is what is in the bubbles in boiling water and coming off the surfaces, but that the stuff we see is actually water vapor which happens when the steam slightly cools and starts condensing back to liquid drops suspended in the air. Am I just confused?

Thank you
