Applications of the Differential Relationships

The relationships summarized in Table 3.1. expanded to include differences and molar properties, serve as the starting point for many useful thermodynamic calculations. An example is the calculation of AZ for a variety of processes in which p, V, and T are changed.e For any of the extensive variables Z = S, U, H, A or G, we can write 

We then substitute our differential expressions from Table 3.1 into equations (3.52) or (3.53) and integrate to get AZ.
