ENTROPY DECREASES Energy + energy Energy is made available to do work as order decreases in the system. ENTROPY INCREASES 8 Energy in a narrow sense... “Free Energy” •  Energy AVAILABLE to do Work •  G (Gibbs free energy) G = H - TS useable energy total energy unusable energy Free Energy In the case of a living system...
