Question

The sprinkling of water slightly reduces the
temperature of a closed room because
(a) temperature of water is less than that of the
room
(b) specific heat of water is high
(c) water has large latent heat of vaporisation
(d) water is a bad conductor of heat

Answer 1

Explanation:

(C) Water has large latent heat of vaporization is correct because:

When we sprinkle water on floor of a room,

water absorps the heat from floor and since it has more kinetic energy now it converts into gas (water vapour) using this heat.
