Which process of sweat gives cooling to the human body?

Answer and explanation

Correct answer: Evaporation

Correct answer: A, evaporation. Sweat is liquid water on the skin. When it evaporates, the water molecules need latent heat to change into vapour, and this energy is taken from the skin and nearby body surface. The loss of heat produces cooling. In humid air, evaporation is slower because the air already contains much water vapour, so sweating may feel less effective. B, compression, means pressing a substance and is not the process that removes heat from sweat. C, friction, generally produces heat rather than this evaporative cooling. D, deposition, is the direct change of vapour into a solid, such as ice, and does not describe sweat leaving the skin. Memory cue: sweat cools only when it can evaporate.
