From next time try using "Ctrl+Shift+N" And the "Ctrl+I"..
It feels like a year time if you go to menu and click them..
What? Im not kidding.. It really feels so.
Btw awesome Videos you make!

"it is not an animal that digs holes in your backyard" :D
best advice ever!
-
I enjoy your lecture, very simple and straight forward,, and you are very good teacher

@khanacademy correct! change of units=change of the number!
-
@megaelliott he just likes sulfur hexafluoride

Not sure why I sat through confusing lectures all semester. Love your stuff, good explanations. I appreciate the work you do.

This comment has received too many negative votes show
just to clarify on your lovely lesson, you used the wrong gas constant for PV=nRT, R is actually a different gas constant which is .0821 L/atm*K, just thought you should know that.

They are the same number. You use .0821 if the units are (liters*atmosphere)/(kelvin*moles). You use 8.3 if the units are joules/(kelvin*moles).
