Homework Statement
Just wanted to find some clarity regarding this subject. In my textbook, it states that Q = nCvdT for constant volume and Q = nCpdT for constant pressure.
However, one of the TA's in my classes were telling us how dU = nCpdT for constant pressure and dU = nCvdT for constant volume.
Which is right? I'm majorly confused right now.
Homework Equations
dQ = dU + dW
The Attempt at a Solution
No solution really needed, I just want some clarification as to which is right. I know that for constant volume processes, the work will be 0 and therefore dQ = dU which would mean they can BOTH equal nCvdT?
But what about nCpdT? That's what I'm confused about. Thanks for any help!
