CBSE Class 9 Answered
Why do people sprinkle water on roof after hot summer day?
Asked by Virender | 25 Apr, 2016, 08:56: PM
Expert Answer
In hot summer day, the roof becomes very hot consequently making the inside of home also very hot.
When water is sprinkled on roof, it absorbs heat from it's surrounding, here from hot roof to get vaporise from liquid phase to gaseous phase.
Thus, the roof becomes cooler which helps in keeping the inside of home also cooler.
