Hank, I want to thank you for this series of videos (which I have been bingeing for the last 2 hours. I've been a professional brewer for a number of years, and recently I decided to enroll at my local college to study biochemistry in order to further my career. I start Chemistry lab work next week. Your sign-off message of never giving up on one's dreams because of the potential that they offer, even for a 30-year old working-class scientist, is just what I needed to hear right now. The cost of tuition is a dear price to a person who works full time, and I hesitated to pay it willingly. But now I find myself resonating strongly with the story of Van Der Waals, old as it is. I have followed SciShow since the early days purely for entertainment, but now you have given me something more than either entertainment or academic knowledge, you have offered me encouragement. Thank you.
(P. S. Can you recommend any high-quality Periodic Tables for home use and display? I can see you are a fan)

i dont get the constants a, b from the van der waals equation, can anyone please clarify how they are derived. besides, in the video hank says that the unit for pressure correction factor of N is kilopascals per liter square, mole square however, in the calculation it is written as kpa. L-2/mol-2. Help!

I plugged in everything as written and got 11 700 kPa, however you state 12 200 kPa - 11 800 kPa =/= 3 000 kPa, but 400 kPa and my calculation would be a difference of 500. suggestions as to my error or which indeed is correct?

Why is the R value for ideal gases different in some problems? In the classroom, we calculate the R value as 0. 0821 and this universally used for the ideal gas equation. Could it be a difference of units?

HAH well, we aren't all rich, Hank my man.
Being an adult is all about living on an allowance, one you have to figure out yourself and boy is it stressful.

molecular attraction induce a decrease in pressure, yet in the equation pressure is corrected with addition of factors. Should'nt it be a soustraction? i'm confused

I didn't know that studying for my chem test would bring a life lesson and motivation talk with it but u know what I'm not mad and of course Hank is the one to do it

Great stuff, but it's impossible to listen to it without being native English speaking. Too fast and illegible. Learn something from the announcer guy.

you make a mistake, the pressure difference between the ideal gas and real gas in the case you mentioned is 300 kPa, you said is 3000 Kpa
