Which of the following correctly explains why clothes dry faster on a windy day?

The correct answer is Wind removes the water vapour from the clothes’ surroundings..

Key Points

• Wind increases air circulation around the clothes, which helps remove water vapor from the immediate surroundings.
• This process accelerates evaporation as the saturated air near the clothes is replaced with drier air.
• The continuous removal of humid air prevents the water molecules from re-condensing on the clothes.
• Evaporation is faster when the air around the clothes is less humid, and wind plays a crucial role in maintaining this condition.
• Wind acts as a natural dryer by promoting effective evaporation, even in cooler temperatures.

Additional Information

• Evaporation: The process where liquid water turns into vapor, often influenced by temperature, humidity, and air movement.
• Humidity: The amount of water vapor present in the air. Lower humidity levels allow faster drying of clothes.
• Air Circulation: Movement of air, such as wind, helps replace saturated air with dry air, accelerating evaporation.
• Temperature and Drying: Higher temperatures typically speed up evaporation, but wind can have a significant drying effect even in cooler conditions.
• Role of Wind: Wind enhances drying by reducing the concentration of water molecules around the surface of wet clothes.
