Non equilibrium conditions and temperature

  1. Jan 22, 2008 #1
    For non-equilibrium conditions, can temperature be defined?
    Does this relate to the zeroeth law of thermo?

    Thanks!

    Sometimes a temeprature can be formally defined: the temperature of a 2-state atomic population during inversion, for example.

    Generally, it is not possible to assign a unique temperature.
