Question

on a hot sunny day, why do people sprinkle water on the roof or open ground?​

Answer 1

Answer:

• We sprinkle water on the roof or open ground in hot summers. This water requires latent heat of vaporisation to change from liquid state to vapor state. It evaporates or vaporises by taking the large amount of latent heat from the roof or ground and surrounding air.

Answer 2

Answer:

People sprinkle water on the roof because it gets evaporated due to the heat and takes away heat along with it thus cooling the surrounding area. This is based on the fact that evaporation causes cooling.
