Quick Definitions:


Question Answer
Entropy ProductionAmount of entropy produced in unit volume over unit time
Stationary StateStable system, NOT in equilibrium though. Must be supplied with energy to maintain state. Minimum production of entropy
Thermodynamic EquilibriumA system in thermal, mechanical and chemical equilibrium.
Prigogine PrincipleAt fixed external conditions, an open system will tend towards a state with minimum production of entropy
FluctuationsSmall random deviations from equilibrium due to probability
Generalized Le Chat's PrincipleClose to the stationary state of an open system, fluctuations will intiate flows that restore stationary state
