Entropy and The Second Law of Thermodynamics
... The total entropy of all systems taking part in a process never decreases. It remains the same only if the process is quasistatic. The entropy of an isolated (closed) system can never decrease. It remains the same only if all internal processes are quasistatic. Note that real processes are never exa ...
