... C is known as molar specific heat capacity of the substance. Like s, C is independent of the amount of substance. C depends on the nature of the substance, its temperature and the conditions under which heat is supplied. The unit of C is J mo1–1 K–1. As we shall see later (in connection with specifi ...

... All these results come from the functional form (3.26) in which the entropy depends on space and time implicitly through the functions h ( x, y, z, t ) and P ( x, y, z, t ) . The entropy does not depend explicitly on x, y, z, or t . Take the substantial derivative, D Dt , of the entropy. The resul ...

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 ...
