Model - Entropy as a State Function Entropy, S, as with all other state functions like internal energy, E, and enthalpy, H, is a function of the state of a system. Because measuring the absolute state of a system more difficult than measuring the changes in its states, it is the change in entropy, ΔS, in which we will be interested. This means the only aspects that will interest us will be the difference in the final and initial entropies...
