Abstract:
A composite system consisting of two identical ideal gases separated by a movable, frictionless, diathermic piston is used to illustrate the application of different extremum principles in thermodynamics. The time evolution of the system from an initial constrained equilibrium state to the final equilibrium state is analysed by means of a very simple phenomenological model.
