Question

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 of water is high
• C. water has large latent heat of vaporization
• D. water is a bad conductor of heat

Answer 1

Answer: (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.
