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.

mopping the floor is also an eg.....

MOPPING,SWEATING,EARTHERN WARE POT,ETC. CAUSES COOLING.

When we put perfume or acetone on our palm...
The perfume/acetone takes away the heat from our palm and evaporates and thus cause cooling effect.
 
*Hope you got your answer. If not you can ask again...;)*

cooling of  tea 

too
 

1)water in earthern pots during summer
2)vaporisation of water from leaves
3)easier to drink tea in saucer than in cup
THATS ALL I KNOW

AND ALSO WEARING COTTON CLOTHES IN SUMMER

what is observed when alum is put on wounded cut and what is this process known as?

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.

Example : 1.when we spray a deo on our hand.

2.Aetone

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
