A survey of statistical mechanics as it pertains to molecular simulation
... A statistical mechanics of isolated systems is not convenient. We need to treat systems in equilibrium with thermal, mechanical, and chemical reservoirs. Much of the formalism of statistical mechanics is devised to permit easy application of the postulates to nonisolated systems. This parallels the ...

Entropy Systems Theory
... The phenomenon of entropy was originally observed in thermodynamic systems such as heat baths. An isolated system is one that is closed to inputs of both matter and energy. This means that since no new heat energy can be added, the system can never become hotter, but can only remain the same tempera ...

The fact that a process is spontaneous does not mean that it will occur at an observable rate. It may occur rapidly, at a moderate rate, or very slowly. The rate at which a spontaneous reaction ...

notes on thermodynamic formalism
... Interactions between systems are said to be reversible if they proceed infinitesimally slowly as a result of infinitesimal differences in temperature or pressure. Thus an infinitesimal change in the temperature of pressure of the systems would cause the interactions to occur in the opposite directio ...
