That is, the Shannon '''entropy''' of a macrostate would be directly proportional to the logarithm of the number of equivalent microstates (making it up). Assuming (by the fundamental postulate of statistical mechanics), that all microstates are equally probable, this means, on the one hand, that macrostates with higher '''entropy''' are more probable, and on the other hand, that for such macrostates, the quantity of information required to describe a particular one of its microstates will be higher. Ludwig Boltzmann defined entropy''' as being directly proportional to the natural logarithm of the number of microstates yielding an equivalent thermodynamic macrostate (with the eponymous constant of proportionality).# A measure of the disorder present in a system.

That unusable energy is given by the entropy''' of a system multiplied by the temperature of the system.'' ''(Note that, for both Gibbs and Helmholtz free energies, temperature is assumed to be fixed, so '''entropy is effectively directly proportional to useless energy.) The thermodynamic free energy is the amount of work that a thermodynamic system can perform it is the internal energy of a system minus the amount of energy that cannot be used to perform work.A measure of the amount of energy in a physical system that cannot be used to do work.
