_NOTOC_ The temperature of a system in classical thermodynamics is intimately related to the zeroth law of thermodynamics; two systems having to have the same temperature if they are to be in thermal equilibrium. By making use of the ideal gas law one can define an absolute temperature
having the SI units of Kelvin (named in honour of William Thomson).
