A cubic metre of air at 0degreesC and 1 atm is compressed reversibly to 10 atm.

(a) What is the final temperature if it is compressed adiabatically?

(b) How much heat must be removed if it is compressed isothermally?

I understand what the two different terms mean, but I just don't seem to be able to answer this for some reason. If someone could explain how to go about answering it that would be really helpful!

Thanks

2. Relevant equations

3. The attempt at a solution

For (a) I tried to use the relationship that T^gamma x p ^ (1-gamma) is constant, where gamma = Cp/Cv, but that didn't work at all.

For (b) I thought I'd take dU = -pdV and integrate it with respect to dV with p = 1/V but (obviously I guess) this didn't really work.

Any help in the way of what method to use, etc, is appreciated!

Thanks
