Answer: 54.418 kJ amount of heat required to completely melt the sample.
Step-by-step explanation:
Mass of water = 200 g
Initial temperature of the water = 0°C
Final temperature of the water = 65°C
Temperature change =

Specific heat capacity =


(1 kJ = 1000J)
54.418 kJ amount of heat required to completely melt the sample.
