Question

latent heat of vaporization of water is 539 kilo calorie/kg(or 22.6?10^5J).what is meant by this statement?

Answer 1

Dear Student,

Latent heat = 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 22.5×10^5 j/kg or 539 Kc/kg means this all heat must be required to convert a water from liquid state to vapour state .
