Question

what is latent heat of fudion and latent heat of evaporation

Answer 1

Hey!

Latent heat of fusion is the heat required when a solid is converted into liquid or vapor or a liquid  into a vapor without any change in temperature.

When a liquid substance changes into a vapor then the energy absorbed without any change in temperature is called latent heat of vaporization or evaporation.

Hope it helps^^

Answer 2

Definition of latent heat of fusion. 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.

Latent heat of vaporization is a physical property of a substance. It is defined as the heat required to change one mole of liquid at its boiling point under standard atmospheric pressure. It is expressed as kg/mol or kJ/kg. ... The heat of vaporization of water is about 2,260 kJ/kg, which is equal to 40.8 kJ/mol.

Hope you will understand :)
