An amount of heat is added to ice, raising its temperature from ?10°C to ?5°C. A larger amount of heat is added to the same mass of liquid water, raising its temperature from 15°C to 20°C. From these results, we conclude that:
A. overcoming the latent heat of fusion of ice requires an input of energy
B. the latent heat of fusion of ice delivers some energy to the system
C. the specific heat of ice is less than that of water
D. the specific heat of ice is greater than that of water
C. the specific heat of ice is less than that of water
