For 10 points, name this quantity measured in Kelvins or degrees Celsius.
Two forms of this quantity make up the horizontal and the curved axes of a psychrometric chart. For an ideal gas, the volume expansivity, symbolized beta, equals one over this quantity. The efficiency of a Carnot cycle equals one minus the ratio of this intensive quantity for the two reservoirs, while RMS velocity of a gas is directly proportional to the square root of this quantity. Entropy is zero for a crystal when this quantity is also zero, according to the third law of thermodynamics. This quantity varies directly with pressure and volume of an ideal gas. For 10 points, name this quantity measured in Kelvins or degrees Celsius.
