WebNo headers. The three TdS equations have been known to generations of students as the “tedious equations” − though they are not at all tedious to a true lover of thermodynamics, because, among other things, they enable us to calculate the change of entropy during various reversible processes in terms of either dV and dT, or dP and dT, or dV and dP, … WebApr 9, 2024 · where Cp represents the specific heat at constant pressure; dH is the change in enthalpy; dT is the change in temperature.
