Entropy as heat:  We also defined entropy in terms of the heat released by a system that is not available to do work.  When this heat is divided by T, the result is a state function.

      deltaS = q/T.

After working out expressions for DeltaS at constant pressure, temperature, and volume pathways, we proved to ourselves that entropy is a state function using the Carnot cycle.
