Answer:
Because of the large heat of vaporization of water, the evaporation from a liquid surface is a very effective cooling mechanism. The human body makes use of evaporative cooling by perspiration to give off energy even when surrounded by a temperature higher than body temperature.
Explanation:
Vaporization is the name given to the physical transformation from liquid to gaseous. In this transformation there are only changes in the physical character of the matter, that is, after its occurrence, the matter remains with the same constitution (composition). The water goes through the vaporization process that changes from liquid water to water vapor through temperature. Due to the great heat of water vaporization, the evaporation of a liquid surface is a very effective cooling mechanism.
Perspiration, in turn, is a normal and healthy bodily function, which begins to occur a few months after birth. Humans perspire to cool their body temperature. In science, this process is called thermoregulation. When it occurs, the brain sends a signal to more than 3 million glands in the body, which immediately release sweat. Sweat is a liquid composed of water, salts and proteins. As we sweat, this liquid evaporates from the skin to reduce body temperature. The human body makes use of evaporative cooling by perspiration to release energy, even when surrounded by a temperature above body temperature.
