Question

latent heat of vaporization

Answer 1

Latent heat of vaporization is a physical property of a substance. ... 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

The amount required to change the state of a liquid substance into gaseous form is called latent heat of vaporisation.
