The entropy of an isolated system can decrease.

Vedclass · Answer

(D) Entropy $(S)$ is a state function, meaning the change in entropy $(\Delta S)$ between two states depends only on the initial and final states, not the path taken. Thus, option $(A)$ is true.Entropy is defined as a quantitative measure of the degree of disorder or randomness in a system. Thus, option $(B)$ is true.A Carnot engine operates in a reversible cycle. Since entropy is a state function, the change in entropy over a complete cycle $(\Delta S_{cycle})$ must be zero. Thus, option $(C)$ is true.According to the Second Law of Thermodynamics, for any process occurring in an isolated system, the total entropy change must be greater than or equal to zero $(\Delta S \ge 0)$. Therefore, the entropy of an isolated system can never decrease; it can only increase (for irreversible processes) or remain constant (for reversible processes). Thus, option $(D)$ is false.
