Thermodynamic entropy is denoted by the symbol s, and the formula for change in entropy is. Unlike the entropy index defined below, this partial formula describes the diversity in a metropolitan area. For an isolated system, the natural course of events takes it to a more disordered and higher entropic state. The bottom line is that entropy change is a measure of reversibility.
