Question

Derive an expression for isochoric process?

Answer 1

Answer:

For an isochoric process: δQ = vCvmdT (where Cvm is a molar heat capacity at constant volume): Δ S v = ∫ 1 2 δ Q T = v C v m ∫ T 1 T 2 d T T = v C v m ln T 2 T 1 . For an isobaric process: δQ = vCpmdT (where Cpm is a molar heat capacity at constant pressure).
