Answer 1

This is class 8 ICSE Board answer

Answer 2

Answer:

Latent heat of fusion is the heat required to change 1 kg of solid substance into the liquid state at the melting point of the substance. For eg. amount of heat required to melt ice at 0 °°C into the water at 0 °°C, will be known as the latent heat of fusion of ice.

For ice, the latent heat of fusion is 334 kJ kg-1. This means that 334 kJ of heat is required to convert 1 kg of ice at 0 °°C into 1 kg of water at 0 °°C.
