In a previous paper1 we laid the physical foundations for the atomic and molecular interpretations of the “internal variables” in theories of irreversible thermodynamics. This we did using the concepts of “deformation kinetics” as a point of departure. The results were two-fold:
Non-linear equations of evolution of internal variables were established.
Phenomenological parameters were given an atomic or molecular identity.
