Question

Pls give me 10 examples of evaporation causes cooling with explanation

Answer 1

1) our Palm feels cold when we put some perfume on it because particles of perfume absorb heat energy from our hands and evaporates causing cooling effect on our hands 2) a desert cooler cools better On a hot dry day Because evaporation is more on hot dry day as temperature is high and humidity level is low. Also evaporation leads to cooling

Answer 2

Hi friend....

When Evaporation occurs it absorbs all the heat from the surrounding and hence. Evaporation causes cooling.

Some examples are as follows:

1.when tea is poured into a saucer when it is very hot it is exposed to a large area and causes evaporation n the tea becomes cool.

2.In summer seasons the water gets cool in a earthen pot because it has fine pores in it through which water seeps out gets evaporated .

3.when we sweat n sit under a fan we feel cool .

4. doctors advice patients with fever to keep a wet on their fore head.

5. A wet khus khus screen hung at the door of the room keeps the room cool.

Hope it help's U..!!
