This quantity, for systems with geometrical frustration, is nonzero at absolute zero.
This quantity, for systems with geometrical frustration, is nonzero at absolute zero. The fluctuation theorem gives the probability that over time this quantity decreases. An experimentally useless form of the Clausius-Clapeyron equation has the slope of the coexistence curve equal the change in this quantity over the change in volume. Allowing different gases to (*) mix increases this quantity. This extensive quantity is the conjugate variable of temperature and, for an ideal gas, its change is the focus of the H theorem. This quantity is equal to the Boltzmann constant times the logarithm of the number of microstates. For an irreversible process, this quantity increases over time according to the Second Law of Thermodynamics. For 10 points, name this quantity, a measure of a system's disorder.
