Evaporation causes cooling?how is this possible
Answers
Answer:
because of latent heat of vaporisation
Answer:
of human perspiration. We have pores in our skin from which liquid water internal to our skin is escaping and converting to water vapor in the air. As this happens, it cools down our skin surface. This happens almost constantly to one degree or another. When we are exposed to an environment that is hotter than what is comfortable for us, the degree of perspiration or evaporation increases. And it follows that the cooling effect increases. The more water molecules that are escaping from the liquid phase from our skin surface and from our pores, the more cooling effect there is. Again, this is because the liquid molecules, as they escape and become vapor, require heat and they take it with them.
