Sažetak
Spontaneous transitions of an isolated system from one macroscopic state to another (relaxation processes) are accompanied by a change of entropy. Following Jaynes’ MaxEnt formalism it is shown that practically all possible microscopic developments of the system, within fixed time interval, are accompanied by the maximum possible entropy change. In other words relaxation processes are accompanied by maximum entropy production. Applying the maximum entropy production principle to the systems close to the equilibrium a complete picture of linear non-equilibrium thermodynamics is derived. A logarithmic dependence of the diffusion (heat) flux on the gradient of concentration (temperature) is predicted. For small gradients of concentration or temperature, the theory reduces to the standard laws of gas diffusion and thermal conductivity of insulators.
