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.
Dimension
Temperature is frequently, at elementary levels at least, considered as one of the fundamental dimensions of physics.
In dimensional analysis it is usually assigned the symbol $\Theta$.
