Fans move air around, creating a cooling sensation. It might seem strange to use a fan to dry wet clothes since fans usually make things cooler, not warmer. Normally, when water evaporates, it requires heat, not cold air. What do you think about this?
Fans help dry wet clothes faster because they increase air movement around the wet clothes. The chapter states on page 13 that 'with the increase in the movement of air, water evaporates faster.'
When a fan blows air over wet clothes, it continuously replaces the humid air near the clothes with drier air. This increases the rate of evaporation.
The cooling sensation we feel from fans is actually due to evaporation of sweat from our skin. Similarly, the increased air movement helps water evaporate faster from wet clothes, drying them more quickly.
Explanation
The chapter explains on page 13 that 'clothes dry faster on a windy day. With the increase in the movement of air, water evaporates faster.' Fans create this same effect by increasing air movement. The cooling effect mentioned in the question is actually caused by evaporation itself, as stated on page 14: 'Water seeps through the surface of the earthen pot and evaporates, which imparts a cooling effect.' The fan does not make things cooler by itself—it increases evaporation, and evaporation causes cooling.
Solution Steps
Fans increase air movement around wet clothes
Increased air movement causes water to evaporate faster
Fan replaces humid air near clothes with drier air
