Heat of Vaporization-the amount of heat required to convert unit mass of a liquid into the vapor without a change in temperature. For water at its normal boiling point of 100 C, the heat of vaporization is 2260 J g-1. 2260 J of heat must be absorbed by the water. Conversely, when 1 g of steam at 100 C condenses to give 1 g of water at 100 C, 2260 J of heat will be released to the surroundings.
When the skin excretes water (sweats) through the sweat glands, the evaporation of the water can help cool the skin as it absorbs heat from the body to change from liquid to v â¦ apor. The Heat of Vaporization of water at, hmmm, let's say 104 Â°F (40 Â°C) is 43.350 kJ/mol or 2408 J/g.vaporation is the vaporization that takes place only on the  surface of a liquid. Evaporation takes up energy-and it takes up  that energy from the warm surface of your s â¦ kin. Thus, when sweat  evaporates, it takes heat from your skin, cooling it.
