Hi there.

I was wondering if someone could help.

I have been asked 2 small questions for homework, which i am stuck with.

Firstly, show that cp-cv = r.

I have managed to do this as the teacher has gave us some clues in class.

THe second question is show that gamma = Cp/Cv ?

Would anyone be able to help me out with the second question?

Ideally id like someone to do the question for me, and add their own comments below each line so i could follow it?

thanks in advance,

regards

Adam
