Question

latent heat of vaporization defination ​

Answer 1

Answer:

The enthalpy of vaporization, also known as the heat of vaporization or heat of evaporation, is the amount of energy that must be added to a liquid substance to transform a quantity of that substance into a gas. The enthalpy of vaporization is a function of the pressure at which that transformation takes place.

Answer 2

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.

$\mapsto$ The heat of vaporization of water is about 2260 kJ/kg which is equal to 40.8kg/mol.
