Question

What is latent heat of fusion of a solid? How much the latent heat fusion of ice in SI units?

Answer 1

The quantity of heat required to convert one kg or mass of solid into its liquid form is called latent heat of fusion.

Answer 2

Latent heat of fusion: The heat ene- rgy required to convert 1 gram of so- lid completely into liquid at constanttemperature is called latent heat of fusion. 

Similarly, while ice melts, it remains at 0 °C (32 °F), and the liquid water that is formed with the latent heat of fusion is also at 0 °C. The heat of fusion for water at 0 °C is approximately 334 joules (79.7 calories) per gram, and the heat of vaporization at 100 °C is about 2,230 joules (533 calories) per gram
