Question

Define specific latent heat of fusion of ice. State its magnitude in calories and joules.

Answer 1

Specific Latent Heat of Fusion of Ice:

1. The term “Specific latent heat of fusion of ice” denotes the heat energy required to convert the unit mass of ice to water without the change in temperature (or ice at 0°C to water at 0°C).
2. The amount of heat energy required to melt 1kg of ice at 0°C to form water at 0°C is termed as specific latent heat of fusion of ice.

Magnitude of Specific Latent Heat of Fusion of Ice:

1. The magnitude of specific latent heat of fusion of ice in calories is 80 calories g^-1.
2. The magnitude of specific latent heat of fusion of ice in joules is 336000 Jkg^-1.
