when you sweat the sweat eventually vapors into the air (after a while) and it cools the area of where it vapors on the organism.
The latent heat of evaporation
Water has a high heat of vaporization
High heat of vaporization. It requires a great deal of energy to break the H bonds in water.
Because of strong hydrogen bonding.
The high heat of vaporization, the implication being of water, facilitates life by allowing for efficient heat transfer from an organism to the environment during overheating. This is the case for sweat in terrestrial animals, which evaporates from the skin of a warm animal. The high heat of vaporization forces the outermost layers of the epidermis to lose the equivalent amount of thermal energy, cooling the skin.
Heat of Vaporization id the amount of heat needed to transform a liquid into a gas while not raising its temperature.
high heat vaporization of water
Because the latent heat of fusion and latent heat of vaporization are very high
Heat of vaporization is the amount of heat energy required to change the state of a substance from liquid to gas.q = m·ΔHv, where q = heat energy in Joulesm = mass in gramsΔHv = heat of vaporization in J/g
thermol
The heat of vaporization of water is 2260 joules per kilogram.
Water is expected to have the highest heat of vaporization among common substances.
