Vedclass · Answer

(B) Entropy is a measure of the disorder or randomness of a system. When a substance changes from a liquid state to a solid state,the particles become more ordered,leading to a decrease in entropy $(\Delta S In the freezing of water,liquid water molecules (which are more disordered) transition into a rigid crystalline structure of ice (which is more ordered). Therefore,the change in entropy is negative. Hence,option $(B)$ is correct.

Among the following processes,for which process is the change in entropy $(\Delta S)$ negative?
