"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.

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!

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?

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?

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.

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"

Best video on Vapor pressure so far!
