Q. The sprinkling of water reduces slightly the temperature of a closed room because
A) Temperature of water is less than that of the room
B) Specific heat if water is high
C) Water has large latent heat of vaporisation
D) Water is a bad conductor of heat
Explanation
(c) The latent heat of vaporisation of water is large, so when water is sprinkled over a large area, evaporation takes place, thus, causes cooling.
