Second law of thermodynamics
The Second Law of Thermodynamics states that the state of entropy of the entire universe, as an isolated system, will always increase over time. The second law also states that the changes in the entropy in the universe can never be negative.
Following are the statements of second law of thermodynamics:
(i) All spontaneous process is irreversible in nature.
(ii) The net entropy of the universe in any natural process always increases and tends to acquire maximum value.
(iii) In reversible process, the sum of entropies of system and surrounding remains constant but in an irreversible the total entropy of the system and surrounding increases.
