The correct option is (c).
Explanation
Evaporation is a surface phenomenon wherein a liquid changes into a vapour at any temperature below its boiling point. The rate of evaporation is determined by factors such as surface area, temperature, humidity, and wind speed.
Statement-wise Analysis
- Statement 1 is Correct: Clothes dry faster on a windy day because the increased movement of air carries water vapour particles away from the wet surface. This maintains the concentration gradient necessary for continued evaporation.
- Statement 2 is Incorrect: An increase in wind speed does not cause water vapour to accumulate; instead, it disperses the vapour particles. Accumulation of vapour near the surface would increase local humidity and slow down evaporation.
- Statement 3 is Correct: As the wind moves water vapour particles away, the amount of water vapour in the immediate surroundings decreases. This reduction in local humidity allows more liquid particles to escape into the vapour state, thereby increasing the rate of evaporation.
Key Takeaway: Increased wind speed enhances the rate of evaporation by moving water vapour away from the liquid surface, thereby decreasing the humidity in the immediate surroundings.
