Query: Nonequilibrium translational effects in evaporation and condensation   This paper shows how mesoscopic nonequilibrium thermodynamics can be applied
to condensation and evaporation. By extending the normal set of thermodynamic
variables with two internal variables, we are able to give a new theoretical
foundation for a mechanism of condensation that has been proposed from
molecular simulation results. The flux does not follow a simple Arrhenius
formula for small activation energies which are relevant here.
