Define – (a) latent heat of fusion (b) latent heat of vaporization.
Answers
Answer:
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.
