Vedclass · Answer

(A) At room temperature,water is more stable than ice because ice spontaneously melts into liquid water. Thus,the Assertion is true.Entropy is a measure of the randomness or disorder of a system. Liquid water has a more disordered structure compared to the highly ordered crystalline structure of ice,meaning liquid water has higher entropy. Thus,the Reason is true.According to the second law of thermodynamics,for a spontaneous process at constant temperature and pressure,the Gibbs free energy change $\Delta G = \Delta H - T\Delta S$ must be negative. Since the melting of ice is spontaneous at room temperature,the increase in entropy $(\Delta S > 0)$ contributes to making $\Delta G$ negative,thereby explaining the stability of the liquid state. Therefore,the Reason correctly explains the Assertion.

Assertion : Water in liquid state is more stable than ice at room temperature.
Reason : Water in liquid form has higher entropy than ice.
