please give me some examples from daily life where evaporation causes cooling effect
1.During hot summers,the water is usually kept in the earthern pot to keep it cool.Water is cooled in the pot since the surface of the pot contains large pores and water seeps via these pores to outside of pot. This water evaporates and takes the latent heat for vaporisation hence retaining the water inside pot to be cooled.
2.Especially in villages,people often sprinkle water on the ground in front of their homes during hot summers.
3.Water vaporisation from leaves of trees also cools the surroundings.
4.A desert cooler cools better on a hot and dry day.
5.It is a common observation that we are able to sip hot tea(or milk) faster from a saucer than from a cup
6.Wearing cotton clothes in summer days to keep the body cool and comfortable.
7.Put a little of spirit on your hand and wave around, the spirit evaporates rapidly and our hands feels cooler.

Evaporation causes cooling because during evaporation the particle of the liqued absord energy from the surroundings to regain the energy lost during evaporation. the absorbtion of heat from the surrounding makes the surrounding cool.

when a karate player strikes the pile of tiles with his hands he does so as fast as possible . In other words the time taken to strike the piles of tile is very small .As the momentum of hand of a karate player reduces zero when his hands strikes the pile of tiles in very small interval of time therefore a very large force is exerted on the pile . This force is enough to break the piles of tiles
