Solution
The correct option is B evaporation
The phenomenon of change of a liquid into vapour is called evaporation.
The energy is absorbed by the molecules when they convert from a liquid into gas. Thus, the particles left in the liquid state loses energy. As an earthen pot is porous, water reaches the surface of the earthen pot and evaporates. This causes cooling of water inside an earthen pot.
