Why do wet clothes take longer time to dry in the shade than in the sun?

Why do wet clothes take longer time to dry in the shade than in the sun?

Answer: The temperature in the sunny area is higher than in the shade and evaporation takes place at a faster rate at high temperature. Hence, wet clothes dry quickly in the sun..

Why does cold air hold less moisture?

A oft-repeated water vapor myth is that warm air can “hold” more water vapor than cool air because as the air warms its molecules move farther apart, making room for more molecules. But, saying cold air can’t hold as much water vapor as warmer air is at best a metaphor for what happens.

How does temperature affect the rate of evaporation?

Although water can evaporate at low temperatures, the rate of evaporation increases as the temperature increases. This makes sense because at higher temperatures, more molecules are moving faster; therefore, it is more likely for a molecule to have enough energy to break away from the liquid to become a gas.

Why is cold air drier than warm air?

Why Does This Happen? As explained on Web MD, “Warmer air holds more moisture than cooler air. In the winter, the cold air that seeps into your home from the outside has a lower humidity level — meaning that it carries very little moisture.

Why do wet clothes dry faster in summer than in winter?

Clothes dry faster in summers due to high evaporation. In summers, the temperature of the surroundings is high. As a result, the rate of evaporation is also high. Hence, wet clothes dry faster in summers.

What happens to the water when wet clothes dry?

When a wet object dries, it is because the liquid water that is on the object evaporates to water vapor and diffuses out into the air.

Why is cold air so dry?

Cold winter air is dry because it holds less moisture than warm air. Because wintertime humidity is so low, what little moisture that is around is quickly sucked up into the air. The water evaporates and adds moisture.

Can cold air hold more water?

Hot air expands, and rises; cooled air contracts – gets denser – and sinks; and the ability of the air to hold water depends on its temperature. A given volume of air at 20°C (68°F) can hold twice the amount of water vapor than at 10°C (50°F).

Why does warm water evaporate faster than cold water?

Water is made up of tiny molecules that are always moving around. However, cold water will evaporate much slower than it would if it was hot. When water is hot, the molecules move much faster leading to a quicker evaporation.

Do things dry faster in cold or heat?

The higher the temperature of the liquid water, the more molecules there are on the high end of the distribution with enough energy to evaporate. Therefore, the hotter an object, the quicker it dries, even if its temperature is below the boiling point of water.

Do things dry slower in the cold?

For those who live in a humid, overcast, cold, non-windy climate, clothes will dry the fastest when hung indoors in a room with low humidity, high temperature, lots of light, and moving air.
