Enthalpy temperature relationship

WebMar 30, 2024 · μ = Δ T Δ p = − 22 − 31 = 0.7. I think the answer uses the definition of μ that is ( ∂ T ∂ p) H, but this definition assumes the process to have constant enthalpy. But in adiabatic process d H = d U + V d p + w a d, so for d H = 0 we need to have d U + V d p + w a d = 0 which is not possible since pressure is clearly changing and so ...
