For 10 points, identify this quantity which serves as a measure of the amount of kinetic energy contained in a system and is measured in Kelvin.
In the theory of inflation, this quantity scales as the inverse of the scale factor, and the Sutherland equation describes the dependence of viscosity on this quantity. The coefficients of the virial expansion are a function of this quantity only, and for a black hole, this quantity is given by the surface gravity divided by two pi. In the Maxwell relations, this quantity is conjugate to the (*) entropy and is given by the derivative of energy with respect to entropy. In another equation, the product of this quantity and the number of moles is proportional to the product of pressure and volume by the universal gas constant.
