Question

explain two example from our daily life where we feel the effect of cooling due to evaporation

Answer 1

Heya friend,

Evaporation is conversion of liquid to gas on room temperature, where we don't provide any heat to a liquid.

Evaporation causes cooling, we know that. Some daily life experiences where we feel cooling because of evaporation is-

•When we put some sanitiser or nail polish remover on our hand. The liquid takes heat from our hand and evaporates and thus cause cooling.

•When it's too hot, and we are wet in sweat, and suddenly a blow of wind comes, we feel cool. Because it takes the sweat away and we feel cool.

Hope it helps!!

COOLING CAUSED BY EVAPORATION....
1)If we put on little of spirit at the back of our hand and wave it around ,the spirit evaporates rapidly and hand feeka very cold .This is due to the fact that to change from the liquid to the vapour state, spirit requires latest heat if vapouration..


2)Common ex,,,During hot season or summer days ,water is usually kept in an earthen pot to keep it cool.The earthen pot has a large no. of extremely small pores in its walls.Some of the water continuously and takes the latent heat required for vapouration from earthern pot and remaining water.In this way ,the remaining water loses heat and get cooled.

3)At many places, especially in villages ,people often sprinkle water on the ground in front of their homes during the hot summer evening .By losing heat ,the place becomes cool and comfortable.......
