Question

Application of entropy in thermodynamics

Answer 1

Answer:

The entropy of a substance is real physical quantity and is a definite function of the state of the body like pressure, temperature, volume of internal energy. Entropy is a measure of the disorder or randomness in the system.

Answer 2

Answer:

The second law of thermodynamicsstates that the entropy of an isolated system can never spontaneously decrease. ... Note that the spontaneous flow of heat between bodies at different temperatures is always an irreversible process which increases the entropy, or disorder, of the Universe.
