When using the idea gas law to find out how many moles of a certain gas are in the tank, I know we use PV=nRT. But if it gives us the temperature in Celcius, should we convert it to Kelvins?
The point is, the pressure must stay constant for this to happen (Charles' Law). How can the pressure of a gas stay the same when the volume goes up? The molecules must move faster to collide with the container walls...this means that the temperature has to go up!
I have a question. I understand that as the temperature goes up the volume has to go up, since T is proportional to V, but that also means V is proportional to T, but somehow I never could understand how or why would the temperature go up if the volume was increased. Please tell me it has always confused me
It frequently gets friggin' hot here!, even in Edmonton quite a few 31+ (degrees celcius) this summer from July, August, and even a few June's!
Occasionally, some Winter's can be pretty cold though! The coldest I've bore is +/- -41 celcius! =p
With windchill now THAT is friggin' cold! Love the snow though, or should I say the "cool" winters (with little snow, occasionally near-zero shoveling =p ) more than hot summers!

How's that?

Dear Chemguy,
