Increase in entropy of a system represents Correct Answer Degradation of energy

Entropy is a measure of the energy of a system that is unavailable for doing useful work. Increase in entropy of a system leads to increase in randomness and degradation of energy.

The Principle of Increase of Entropy: The entropy of the isolated system is the measure of the irreversibility undergone by the system. More is the irreversibility more increase is the entropy of the system. As such the reversible process is an ideal process and it never really occurs. This means the certain amount of the irreversibility is always there in the system, this also means that the entropy of the isolated system always goes on increasing, it never reduces. Here let us keep in mind that isolated system can always be formed by including any system and surroundings within a single boundary.
