Answer 2

Answer:

People sprinkle water on an open ground or a roof on a hot summer day to keep it cool. When the water touches the hot surface, it uses up the heat to change it's phase from liquid to gas that is, the heat from the ground or the floor gets converted to latent heat of vaporisation.

Hope that helps.
