Question

It is seen that, people get comfort when they sprinkle water on the roof or open ground after a hot sunny day. Why?

Answer 1

Water droplets being sprinkled on the roof in summer can cook the roof down substantially and protect residents from heat.

The water droplets use the heat energy of the roof surface, which is already very hot.

This energy is used by them to rise and hence the molecules can move about freely.

This heat intake by the molecules leads to cooling down of the roof.

The heat is taken up and removed.

Answer 2

Here is your answer
