Wet clothes take longer time to dry on a humid day?
Most Upvoted Answer
Wet clothes take longer time to dry on a humid day?
Introduction:
Humidity refers to the amount of moisture or water vapor present in the air. When the air is already saturated with moisture, it becomes harder for wet clothes to dry. This is because the air cannot absorb more moisture, resulting in a longer drying time for the clothes.

Explanation:
There are several reasons why wet clothes take longer to dry on a humid day:

1. Saturation of Air:
When the air is humid, it already contains a significant amount of moisture. As a result, the air is close to saturation, meaning it is already holding as much moisture as it can. This leaves little room for additional moisture to be absorbed from the wet clothes. Therefore, the drying process slows down.

2. Reduced Evaporation Rate:
Evaporation is the process by which water molecules change from a liquid to a gas state. During evaporation, water molecules escape from the surface of the wet clothes into the surrounding air. However, when the air is humid, it is already filled with moisture, creating a high level of water vapor pressure. This high pressure slows down the evaporation process, making it more difficult for the wet clothes to dry.

3. Lack of Air Circulation:
Humid conditions often accompany still or stagnant air. Without proper air circulation, the moist air surrounding the wet clothes remains in contact with them, hindering the drying process. Air circulation helps to carry away the water vapor released during evaporation, facilitating faster drying. However, in a humid environment, the lack of air movement prolongs the drying time.

4. Absorption of Moisture from the Air:
When the air is humid, it contains a high concentration of water vapor. Wet clothes have a tendency to absorb moisture from the surrounding air, which slows down the drying process. This absorption occurs because there is a difference in vapor pressure between the wet clothes and the humid air. The wet clothes act as a sponge, drawing in moisture from the air instead of releasing it.

Conclusion:
In summary, wet clothes take longer to dry on a humid day due to the saturation of air, reduced evaporation rate, lack of air circulation, and absorption of moisture from the air. These factors collectively hinder the drying process and extend the time required for the clothes to become completely dry.

Wet clothes take longer time to dry on a humid day?
On a humid day the air is full of water vapour. Hence, evaporation is very slow. This is the reason why wet clothes take longer time to dry on a humid day.
