I made it through an honors chemistry course in high school, 4 years of chemistry in my undergrad and now half way through studying for my DAT exam and I have NEVER EVER understood the vapor pressure concept. BUT NOW, after watching this video, I cannot believe that professors needed to make this topic so confusing! Your video was so helpful. Thank you!!!!
I super rarely take the time to comment on videos. But i cant stop myself from commenting for this video. Because I really want u to know how much this helped. My rpof made it sooo complicated. It was like a puzzle that finally came together... now i understand (viscosity, vp, bp, mp, surface tension )'s correlation with Inter molecular Forces and how to solve those problems JUST BECAUSE OF THIS ONE SHORT VIDEO......u r a genius. THANK YOU.....
Oh my God, thank you so much for explaining this. I really dont understand why professors explain things in a way that is unnecessarily complicated. Thank you!
damn 10 years and i only found this now? NEVRR in my life did i ever understand vapour pressure and theres this video not even 5 minutes long DOES the job!!!!
I watched 5 videos, made like 50 google searches trying to get the basics of vapor pressure and intermolecular forces, and your video taught my dumbass both concepts in 4.5 minutes. Thank you!!
Wow! Thank you so much. The concept of vapor pressure was really vague and I could not visualize it, but your explanation helped me a lot!!!! Thank you so much!!!
PLEASE PLEASE PLEASE answer. You said hydrogen bonds were the strongest intermolecular force And then you said hydrogen bonds were the weakest intermolecular force WHAT DOES THIS MEAN
well as the temperature increases, the pressure increases and if the temperature decreases then the pressure decreases so it depends on the temperature given to you. ** Someone correct me if I am wrong **
Enthalpy of Vaporization is the amount of energy required to turn a given amount of liquid into a gas. This video is talking about intermolecular forces and how they affect vapor pressure. Stronger IMFs=Lower Vapor Pressure. Stronger IMFs also relate to a higher amount of energy needed to vaporize a given substance, since the stronger IMFs drive the molecules to be more physically attracted to each other, thus making it more difficult to overcome those forces (and ultimately eliminating those forces enough to "evaporate" a substance). Also, Hvap will be measured in Joules (or kJ), while this is just conceptually based.
