The Gibbs-Duhem equation describes the change in chemical potential as P D V and this quantity times D T change. In black holes, this quantity is the area of the event horizon divided by four times the Planck Length. The Gibbs paradox shows that particles must be indistinguishable because otherwise this quantity would decrease in one step. This quantity may be given by Boltzmann's constant times the natural log of the multiplicity. Exothermic reactions may fail to be spontaneous if they also decrease this quantity, whos
The Gibbs-Duhem equation describes the change in chemical potential as P D V and this quantity times D T change. In black holes, this quantity is the area of the event horizon divided by four times the Planck Length. The Gibbs paradox shows that particles must be indistinguishable because otherwise this quantity would decrease in one step. This quantity may be given by Boltzmann's constant times the natural log of the multiplicity. Exothermic reactions may fail to be spontaneous if they also decrease this quantity, whose universal decrease is prohibited by the second law of thermodynamics. For 10 points, name this physical quantity that always increases and roughly is the "disorder" of the system.
