| Entropy: Entropy in physics is a measure of the disorder of a system. It is a thermodynamic quantity that is denoted by the letter S and has units of joules per kelvin (J/K). Entropy is often described as a measure of the number of possible microscopic configurations of a system that are consistent with its macroscopic state. The higher the entropy of a system, the more disordered it is.
