1.
It shows that Particles of water have less forces of attraction between them.
2.
By sprinkling water on rooftop in summers, as you know roof can be hot due to sun rays, when water sprinkled, it evaporates by taking enough heat from the rooftop's surface which decreases it's temperature and make the surface suitable for walking.
3.
(1) By increasing surface area.
(2) By increasing temperature or putting it on the surface where sun rays are falling.
(3) By increased wind speed which take away it's or water particles away with it.
Hope it helps You ;)
