Now if we consider the condensation process, i.e. if the cyclic process started by increasing the external pressure, which equals PH2O(T), by Δ P, it is possible to show that, for a cycle, the permanent change in the external energy of the heat reservoir is V ΔP. Thus, as ΔP approaches infinitesi ...
