absolute temperature 
noun
A temperature measured from absolute zero in kelvins. (Symbol: T) Entropy is a thermodynamic quantity, its value is equal to the amount of heat absorbed or emitted divided by the thermodynamic temperature (the absolute temperature, in Kelvin)....
- At constant pressure the volume of a given mass of gas is directly proportional to the absolute temperature, that is the temperature expressed in Kelvin.
- In this particular system, the absolute temperature of an ideal gas is directly proportional to the average kinetic energy of the molecules.
