WebWe shall therefore choose H as our state function and P and T as our independent state variables. That is we shall write H = H ( P,T ), so that (10.3.2) ( ∂ T ∂ P) H ( ∂ H ∂ T) P ( ∂ P ∂ H) T = − 1. The second of these partial derivatives is CP, and therefore (10.3.3) ( ∂ T ∂ P) H = − 1 C P ( ∂ H ∂ P) T. Now (10.3.4) d H = T d S + V d P. That is, WebFrom here, the Joule-Thompson coefficient defined like this is also zero for ideal gas. Another characteristic of ideal gas is the difference between Cp and Cv. It was the gas constant R before. Let’s derive this relationship here. Cp is (dH over dT) at constant P and Cv is (dU over dT) at constant v. Let’s express the (dH over dT) first. chunky milk commercial mint mobile https://megaprice.net
