Non-equilibrium temperature is defined independently of the characteristics of any particular substance. The relation defining absolute non-equilibrium temperature is shown to be similar to the definition of absolute equilibrium temperature proposed by Kelvin. No a priori empirical non-equilibrium temperature is introduced. Moreover, for the particular case of an elastic body a unique non-equilibrium entropy is shown to exist.
