The way to approach it is, first, to think about evaporation. This is something we're all familiar with. We get hot, we sweat, the sweat evaporates. It is the total heat contained in 1 kg of steam. It is the sum of the enthalpy of the various states, liquid (water) and gas (vapour). Latent Heat of Vaporization. Latent heat of vaporization is the heat consumed or discharged when matter disintegrates, changing state from fluid to gas state ...
