Vedclass · Answer

(B) The molar heat capacity $(C)$ is defined as $C = \frac{dQ}{dT}$.When water is in equilibrium with ice at a constant pressure,the phase transition occurs at a constant temperature (the melting point).Since the temperature remains constant during the phase change,the change in temperature $\Delta T = 0$.However,there is heat exchange $(\Delta Q 
eq 0)$ as the substance absorbs or releases latent heat.Therefore,$C = \frac{\Delta Q}{\Delta T} = \frac{\Delta Q}{0} ightarrow \infty$.Thus,the molar heat capacity is infinite. Option $B$ is correct.
