Explanation:
Detailed explanation-1: -The answer is evaporative cooling. Turning a liquid such as sweat from its liquid state into a gas requires energy. This energy is taken from our body, or sweat, in the form of heat. The resulting heat transfer leads to the desired cooling effect.
Detailed explanation-2: -When evaporation occurs liquid absorbs heat from the surroundings to get converted to its vapour form as a result, there is an overall decrease in the heat leading to cooling of the liquid.
Detailed explanation-3: -The sweat gets vaporized from the skin into the atmosphere, by absorbing heat from the body. Thus the body cools down as it loses heat.
