The value of entropy generation cannot be negative, however the changes in entropy of the system may be positive, negative or zero. The entropy of an isolated system during an irreversible process always increases, which is called the increase of entropy principle. Entropy change can be determined without detailed information of the process. For a reversible process the entropy generation is zero, and the entropy change of a system is equal to the net entropy transfer. The entropy balance is analogous to energy balance relation.

### FAQ

What is Entropy change (Isothermal Process) (With given volumes)?
Entropy change (Isothermal Process) (With given volumes) = Mass of gas * R * ln (Final volume / Initial volume) Where R is Universal Gas Constant and is represented as S2 - S1=m*[R]*ln(Vf/Vi) or Change in Entropy=Mass of Gas*[R]*ln(Final Volume of System/Initial Volume of System). Initial Volume of System is the volume occupied by the molecules of the sytem initially before the process has started, Final Volume of System is the volume occupied by the molecules of the sytem at the time the system is being analysed and Mass of Gas is the mass on or by which the work is done.
