Why do we sprinkle water on the roof or open ground in hot summer.
Asked by RAJDEEP NASKAR | 23rd Jun, 2013, 12:47: PM
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. Hence, the roof or ground becomes cool after losing its heat to water.
