Question :

On a hot sunny day, why do people sprinkle water on the roof or open ground?Submitted on 2/1/2024 | Answered by Vandana Rana

Answer :

On a hot summer day, when we sprinkle water on the roof or open ground, it evaporates quickly because of the heat of the sun.

Evaporation is a kind of vaporization that occurs on the surface of the liquid as it changes into the gas phase. When a molecule gains energy from the surrounding and escapes as the gas molecule, it lowers the internal energy of the surrounding.

Therefore, decreases the temperature of the surroundings.
