Question

what is meant by saying that latent heat of vaporization of water is 22.5 ×10 to the power 5 j/kg?

Answer 1

latent heat = the heat required to convert a solid into a liquid or vapour, or a liquid into a vapour, without change of temperature.

and the latent heat of vaporization of water is 22.5×10to the power 5 j/kg means this all heat must be required to convert a water from liquid state to vapour state .
