This quantity decreases when ionic solids dissolve in water, because the ions become hydrated, although this quantity normally increases when a substance dissolves. The steps of the Carnot cycle keep either temperature or this quantity constant. At constant temperature and pressure, it equals enthalpy minus Gibbs free energy, all over (*) temperature. This quantity is zero only for a perfect crystal at zero kelvin, and it is generally equal to natural log of the number of microstates, times Boltzmann's constant. It cannot decrease spontaneously, by the second law of thermodynamics. For 10 points, name this thermodynamic quantity denoted "S " that represents the amount of disorder in a system.
