Evaporation is a natural process, there are countless examples.
For example, have you ever noticed how a dog hangs its tongue out after running roughly?
The saliva on its tongue evaporates and the tongue becomes cooler, the dog also feels cooler.
Everyone needs fan and feel very cool why?
This is because of the sweat, which is oozing out of the pores in our skin, evaporates in the fan's puff of air. The heat needed for the sweat to evaporate is wrapped up from the entity it comes in get in touch with our body and so we feel cooler.
You know, an adult marching throughout a desert may sweat up to 10 liters of water a day! A human being may lose a lot of body salt through the sweat if he perspires too much. This can result in painful cramps, particularly if he drinks water without adding salt to it.
That is why you must bear in mind to drink lots and lots of water before leaving out on a hot afternoon.
