Question

After a hot sunny day people sprinkle water on the roof or on open ground give an account

Answer 1

Hey mate!!!!

We know that evaporation helps in cooling.
The energy required for evaporation is taken from surrounding area. Since the energy is taken from the surroundings, the surroundings become cool.
So people sprinkle water on the roof or on open ground so that the water absorbs the energy and make the surroundings cool.


Hope it helps dear friend ☺️✌️✌️✌️✌️

Hey mate...!!!
_______________
---------------------------
We know that evaporation causes cooling because of latent heat of vaporization.

So when water is sprinkled on the hot roof or an open ground after a hot sunny day,it evaporates,thus decreasing the temperature of the surroundings.
