Detailed explanation-1: -entropy, the measure of a system’s thermal energy per unit temperature that is unavailable for doing useful work. Because work is obtained from ordered molecular motion, the amount of entropy is also a measure of the molecular disorder, or randomness, of a system.

Detailed explanation-2: -entropy: a measure of the extent to which energy is dispersed throughout a system; a quantitative (numerical) measure of disorder at the nanoscale; given the symbol S.

Detailed explanation-3: -A measure of disorder; the higher the entropy the greater the disorder. In thermodynamics, a parameter representing the state of disorder of a system at the atomic, ionic, or molecular level; the greater the disorder the higher the entropy.

Detailed explanation-4: -Entropy is typically thought of as a measure of disorder or randomness, and it is bound up with thermodynamics – the branch of physics that deals with heat and mechanical work.

Detailed explanation-5: -Entropy is the quantitative measure of disorder in a system. The concept comes out of thermodynamics, which deals with the transfer of heat energy within a system.
