Detailed explanation-1: -The second law of thermodynamics states that the entropy of a closed or isolated system always increases. This means that all available energy is used up and there is no more potential for further useful work. The system becomes disordered and also degraded. This is also called the Entropy Law.

Detailed explanation-2: -The second law of thermodynamics states that the total entropy of a system either increases or remains constant in any spontaneous process; it never decreases.

Detailed explanation-3: -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.

Detailed explanation-4: -The second law states that if the physical process is irreversible, the combined entropy of the system and the environment must increase. The final entropy must be greater than the initial entropy for an irreversible process: Sf > Si (irreversible process)

Detailed explanation-5: -Second Law of Thermodynamics and entropy: the entropy of the universe constantly increases.
