Question

Which requires more heat: 1 g ice at 0°C or 1 g water at 0°C to raise its temperature to 10°C? Explain your answer.

Answer 1

1 gram of ice at 0°C requires additional 80 calories of heat to get converted into water at 0^°C. Then, heat is provided to raise the temperature to 10°C. Therefore, ice requires more heat than water and the additional heat is known as 'Latent heat of fusion of ice'.
