Molar heat capacity of water in equilibrium with ice at constant pressure is __________ Kcal/kg mole . °K

Answer: Option B

During phase changes the temperature of the substances doesn’t increase instead the given thermal energy is used to break the intermolecular bonds and helps the substance to transfer from one phase to other phase. So, during this process the substance seems like an object having infinity thermal capacity because although we are transferring heat but the temperature is not raising.
