Question

11. The latent heat of


vaporization of water is

2.25x106j/kg
3.34106 j/kg
22.5x104 j/kg
33.4x105 j/kg​

Answer 1

Answer:

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.
