Question

Define
Latent
heat
of
Vapouation.​

Answer 1

Explanation:

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. When a material in liquid state is given energy, it changes its phase from liquid to vapor; the energy absorbed in this process is called heat of vaporization. The heat of vaporization of water is about 2,260 kJ/kg, which is equal to 40.8 kJ/mol.

Answer 2

Answer:

The amount of energy required to vaporise 1KG of liquid into gas is called LATENT HEAT OF VAPORISATION
