In thermodynamics, a thermally isolated system can exchange no mass or heat energy with its environment. The internal energy of a thermally isolated system may therefore change due to the exchange of work energy. The entropy of a thermally isolated system will increase in time if it is not at equilibrium, but as long as it is at equilibrium, its entropy will be at a maximum and constant value and will not change, no matter how much work energy the system exchanges with its environment. To maintain this constant entropy, any exchange of work energy with the environment must therefore be quasistatic in nature, in order to assure that the system remains essentially at equilibrium during the process. The opposite of a thermally isolated system is a thermally open system, which allows the transfer of heat energy and entropy. Thermally open systems may vary, however, in the rate at which they equilibrate, depending on the nature of the boundary of the open system. At equilibrium, the temperatures on both sides of a thermally open boundary are equal. At equilibrium, only a thermally isolating boundary can support a temperature difference. (Wikipedia).

Thermodynamics 4b - Entropy and the Second Law II
We compare the reversibility of the Carnot cycle to the irreversibility of the Stirling cycle and find that they may be accounted for by the constancy or increase of transferred heat divided by temperature. We then consider how conservation laws, including the fundamental laws of mechanics
