Assertion: A moist cloth around a steel water container can cool the water.
Reason: Evaporation removes heat from the cloth, which can then draw heat from the container.
Options:
Answer:
A
Solution:
Water evaporates from the wet cloth and takes its latent heat of vaporization from the cloth, which in turn draws heat from the steel container and the water inside. Evaporative cooling keeps the container cooler than the surroundings. Both are true. The Reason gives the physical cause of the Assertion. Correct option: (A).
