Moles in Gas
« on: July 09, 2007, 07:26:15 AM »
Hi,

Does the number of Moles in an ideal gas dictate how much it will expand when heated?

Im after a simple answer.

Cheers in advance.  :-*

pV=nRT
At constant pressure volume of ideal gas is proportional to its temperature

Thanks but that wasnt the answer to the question.
I mean, if 2 different ideal gases, with different number of moles, were heated under the same conditions would the level of expansion be different for the different gases?

Please get back.

Cheers.

Define level of expansion. If you mean ratio of final volume to the starting volume - you may easily derive it from pV=nRT.

OK thanks for your replies. But im not a chem student and i don't want to work out this equation.
I really am looking for a yes or no answer.
Will a gas with a high number of moles expand more than a gas with a low level of moles?
Who can answer this?

Cheers in advance. 8)

For mixture of ideal gases the ideal gas equation also works
