WebSep 1, 2024 · One way to calculate a difference in enthalpy is to use the specific heat, cp c p. For our case, the enthalpy is just a function of temperature only, so. cp = ∂h ∂t = dh dt c p = ∂ h ∂ t = d h d t. and. h2 −h1 = ∫ cp dt h 2 − h 1 = ∫ c p d t. It would be awesome if cp c p would be constant, so that this integral would just be cp ...
