Question

What is latent heat of fusion?​

Answer 1

Latent heat, energy absorbed or released by a substance during a change in its physical state (phase) that occurs without changing its temperature. The latent heat associated with melting a solid or freezing a liquid is called the heat of fusion; that associated with vaporizing a liquid or a solid or condensing a vapour is called the heat of vaporization. The latent heat is normally expressed as the amount of heat (in units of joules or calories) per mole or unit mass of the substance undergoing a change of state.

Answer 2

Answer:

The amount of heat required to change 1 g of a substance at the temperature of its melting point from the solid to the liquid state without changing temperature.
