Derivation of cp and cv

WebJan 15, 2024 · In order to derive an expression, let’s start from the definitions. Cp = (∂H ∂T)p. and. CV = (∂U ∂T)V. The difference is thus. Cp − Cv = (∂H ∂T)p − (∂U ∂T)V. In order to evaluate this difference, consider the definition of enthalpy: H = U + pV. Differentiating … WebIn a constant volume process, TdS = CVdT, so that T ( ∂ S ∂ P) V = C V ( ∂ T ∂ P) V. And in a constant pressure process, TdS = CPdT, so that (13.4.8) T ( ∂ S ∂ V) p = C P ( ∂ T ∂ V) P. Therefore (13.4.9) T d S = C V ( ∂ T ∂ P) V d P + C P ( ∂ T ∂ V) P d V. This is the third of the TdS equations. In summary, then, these are the three TdS equations:
