The Ehrenfest model of diffusion was proposed in order to illuminate the statistical interpretation of this law.
The Ehrenfest model of diffusion was proposed in order to illuminate the statistical interpretation of this law. The Kelvin-Planck statement of it states that the thermal efficiency of a cyclic heat engine must be less than 100% and Claussius' version of this law says that the spontaneous flow of heat from hot to cold bodies is reversible only with the expenditure of mechanical or other nonthermal energy. Stating that, in a closed system, entropy increases, for 10 points identify this law of thermodynamics.
