Vapor Pressure

[chaosdimension100]

I dont get how the pressure can be lower near the surface of the water because then wouldnt the higher pressure from the atmosphere move in and displace the vapor?

and the other thing i dont understand is how in a closed container at equilibrium wouldnt the pressure in the container be higher than atm since you have the pressure due to the vapor as well as the pressure due to the air molecules adding together as per daltons law of partial pressure? would this not mean that volume increases?

[flydiezz]

Thank you for the lecture, but i have a question that is bugging me and i would like to ask my fellow viewers - Is vapor pressure always in equilibrium? If not, can vapor pressure surpass that equilibrium?

[robjows]

I don't understand how the vapour could push the atmosphere if its pressure merely equals atmospheric pressure, wouldn't it need to exceed atmospheric pressure to move it?

@engineerdr The large vp is another way to say that the propane reaches bp faster (bp is very low) relative to the atm pressure. Hope that helps.

[JMLRecordings]

i like his v at 7:44 ----->gi-en Lol

I won't lie to you Sal, if it weren't for you I would have probably failed college. Thank you

So does water or gasoline have stronger IMFs? Water is polar, while gasoline is nonpolar.

Thanks for the lecture!

"if you leave water outside, it will evaporates, even though, hopefully, in your place, is below the boiling point"

LOLOL

Best video on Vapor pressure so far!

at 06:32 who else thought he was going to say "or whatever the f*ck were talking about.."

[engineerdr]

i didnt get how a greater vapor pressure can enhance the evaporation rate.plz help

[engineerdr]

nice video sir.a cyber student from Pakistan

[theshore465]

one person cannot understand what the instructor is saying

[devothj]

One dude down there does not have a ton of kinetic energy!

[ballsoffury4]

Im so stoneeedddddddddddddddd

[MrDevin666]

@ballsoffury4 And you're watching a chemistry video lmao

[crazyloudjukebox]

This is awesome. And interesting! Good work.

"Hopefully the temperature outside your area is lower than the normal boiling point..."

[0zero0zero]

Thank you so much! I have a test in 30 mins and this video helped a lot!!! Keep up the great work! You explain like a beast :p!

[michaeljs1995]

wow you are a great teacher

[KUVVAlTi]

Can u start all ove agine? cuz i havent understod anything

[michaeljs1995]

@KUVVAlTi is that because you don't speak english?

[hbelm]

Thanks for helping me through Gen Chem, your lectures explain these concepts much better than my text book, much more clear and illustrative.

[nilanjana96]

thank u sooooo much! u made it a lot more clear!earlier i was just confused about the relation b/w bp and vp .and i really love ur teaching style!

[anamarisukhitashvili]

I love your videos! You make everything look simple and formulate them in normal language ! <3

[ani0amira]

thanks!! it do help me how to explain this concept to my students~~

[Diminisch]

Studying for MCAT, this video really helped me with this subject, Thank You!

[nikhilr51]

Whos that one person that disliked this?!

[princehashi]

great explanation luved it

[evelyneskimo]

"the wind blows, and it will blow them alllllll away" (x3)

i love your sal-isms. they make your videos fun to listen to (:

thanks for providing these. im using them to study for my IB chemistry exam coming up in a couple of days. i feel like a master of acid base and PV=nRT.

[VistarMonei]

So much clearer than the notes my Chemistry teacher gave me... I'll be sure to watch these videos before doing my homework for next time, too!

[frogspasm]

Great videos a lot clearer than my textbook.

These videos have helped me a lot. Yhank you very much

[mrlemonbreath]

1 atm is normal boiling and melting points

[YouWM]

I'm a student of Technical Chemistry and know all those concepts, but those videos are so unbelievably intuitive and well explained! Congratulations!

[goose434343]

This helps so much! thank you! just wondering, why do the bands on the last chart bend? it is something to do with the logarithmic graph?

[patilnikh]

Sal, what does 1 atm equal?  boiling or liquid phase?

[16velvet]

thanks!

[jeestudent007]

thanks a lot! man

[nitinbansal2006]

ythx

[DaveHowardvideos]

This is great information and very well explained.

[cousin13pro]

wow thanks man
