Definition:Temperature/Absolute

Definition
Absolute temperature is a measure of the amount of heat energy in a body.

It is defined as:
 * $T = \dfrac 1 k \paren {\dfrac {\partial U} {\partial \ln g} }$

where:
 * $k$ is a constant that relates the mean kinetic energy and absolute temperature of the body $B$
 * $U$ is the total energy of $B$
 * $g$ is the number of possible states in which $B$ can be.
