Question

The entropy __________ in an irreversible cyclic process.
(A) remains constant
(B) decreases
(C) increases
(D) None of these

Answer 1

Answer:

increases

Explanation:

for an irreversible cycle, any entropy that is generated within the system during the cycle is transferred to the surroundings. So, in this case, the entropy of the surroundings increases, but the entropy change of the system is still zero.

Answer 2

Answer:

The entropy increase in an irreversible cyclic process.

Explanation:

Another form of the second law of thermodynamics states that the total entropy of a system either increases or remains constant; it never decreases. Entropy is zero in a reversible process; it increases in an irreversible process.
