Question

Quizplus · Accepted Answer

When ice is melting, it requires energy in the form of latent heat of fusion to break the intermolecular bonds between the molecules. Once all the ice has melted, the energy being supplied starts to raise the temperature of the water. During this process, the temperature of the ice-water mixture does not change until all the ice has melted. Therefore, the temperature of the mixture will remain at 0°C during the melting process. Hence, the correct choice is A) 0°C.

Specific Heat Capacity of Ice = 2,000 J/kg-°C
