Abstract
A recently proposed nonlinear kinetic theory for a dense fluid of square-well molecules reveals the existence of two temperature scales, one associated with kinetic energy and the other with potential energy. The scales are coupled through conservation of energy and, for nonequilibrium states, the temperature scales are not identical. The distinction between the temperature scales affects the value of the bulk viscosity.Keywords
