Hey, Mapes. Thank you for your reply! I come down to this after reading your post: dU=dQ+dW, dU is a state parameter and dQ and dW are process parameters. Therefore, dQ(or Cv(T2-T1) holds for any situations where process is involved. And dU is a result when a new state is reached. In other...

I have a question about the deduction of First Thermodynamic Law. The book that I have is written by Paul A. Tipler and Gene Mosca and it is called Physics: For Scientists and Engineers. The way to deduct it is given here: @constant volume, Qv=Cv(T2-T1) Because W=0, E2-E1=Cv(T2-T1)...
