Answer:
The change in phases from solid ice to liquid water involves a large amount of energy which is about 334 kJ/kg or 6.01 kJ/mol while the temperature during the phase change remains constant
The constant energy or heat required to realize the change in phase from liquid then to gas is known as the latent heat of fusion which is indicated by plateau in the attached temperature to time graph taken at atmospheric pressure.
Between the plateaus are transitional stages where the water temperature in a particular phase (ice, water or steam) rises
