Vedclass · Answer

(D) Entropy $(S)$ is a measure of the randomness or disorder of a system.For a given substance,the entropy follows the order: $S_{(gas)} > S_{(liquid)} > S_{(solid)}$.$A$ decrease in entropy occurs when the system moves from a state of higher disorder to a state of lower disorder.In the process $H_2O_{(g)} \longrightarrow H_2O_{(\ell)}$,the substance changes from a gaseous state (high entropy) to a liquid state (lower entropy).Therefore,this transformation exhibits a decrease in entropy.

Identify from the following physical transformations that exhibits a decrease in entropy.
