-
The sprinkling of water slightly reduces the temperature of a closed room because
-
- temperature of water is less than that of the room
- specific heat of water is high
- water has large latent heat of vaporisation
- water is a bad conductor of heat
Correct Option: C
Water has large latent heat of vaporisation. When it is sprinked over a large area, its evaporation occurs which, in trun, causes cooling.
