The entropy change equals the integral of reversible heat over this quantity.
This quantity is constant in the canonical ensemble, but it varies in the microcanonical ensemble. The maximum value for a coefficient of performance is a simple ratio in this intensive quantity. The reciprocal of this quantity, which is symbolized beta, appears in the exponential of a Boltzmann factor. The energy contributed by each degree of freedom depends only on this quantity. Carnot  (car-NOH) efficiency is one minus the (*)  ratio of this quantity for the two reservoirs. The entropy change equals the integral of reversible heat over this quantity. The two containers sorted by Maxwell's demon have different values for this quantity, which scales with average molecular speed. For 10 points, name this quantity measured on an absolute scale by Rankines or kelvins.
This quantity is constant in the canonical ensemble, but it varies in the microcanonical ensemble.
