Differential equation for enthalpy
WebApr 5, 2024 · The symbol of Enthalpy H is referred to as "delta H". At constant pressure, the equation for the change in internal energy, ∆U = q + w can be written as: ∆U = q P – p∆V. Where q P represents the heat absorbed by the system at constant pressure and – p∆V is the expansion work done due to the heat absorbed by the system. The above ...

WebJan 24, 2024 · 0. I came across the following equation for differential change in enthalpy: d h = c p d T + 1 − β T ρ d P. where β = − 1 ρ ( ∂ ρ / ∂ T) P is the thermal expansion coefficient. I would like to prove this equation for myself, but I'm stuck. I start from. d h = T d s + v d P. and use c p = T d S d T which gives. d h = c p d T + v d P.
