Can clothes dry without any air movement

In summary, even without wind or air movement, clothes can still dry in a large enough room as water will evaporate and slowly diffuse outwards. At absolute zero, clothes would dry well in vacuum due to reduced physical processes and the water vapor's own air movement. This is because at STP, air density is higher than water vapor density. In vacuum, there is not a lot of vapor pressure, causing the water to boil and diffuse out of the clothes.

say there was no wind at all, no air movement. would your clothes still dry?

Yes, if the room were large enough. Water would evaporate from the clothing and slowly diffuse outwards.

even if the air molecules were frozen in space as if it were a solid, would the water still diffuse?

By air movement it was assumed that you meant macroscopic air currents (aka wind), in which case marcusl has already given you the correct answer.

If you are referring to both air and water frozen solid at absolute zero (-273.15 degrees) then could you please repost your question to make that clear.

Clothes would dry extremely well in vacuum.

Diffusion occurs in solids. Vacuum/freeze drying is effective and incorporates sublimation. At absolute zero physical processes are much reduced.

The water vapour would be less dense than the surrounding air, so it would make it's own air movement.

STP air density is about 1.2 kg m^3. Air molecular mass averages about 29 while water is 18. Maybe the bloke's "movement" is buoyancy?

How come?

There's not a lot of vapour pressure - the water would instantly boil

And boiling is just another word for the water molecules diffusing out of the clothes.
 

Related to Can clothes dry without any air movement

1. Can clothes dry without any air movement?

Yes, clothes can dry without any air movement, but it will take longer compared to when there is air movement. Air movement helps to carry away the moisture from the clothes, thus speeding up the drying process.

2. How long does it take for clothes to dry without any air movement?

The time it takes for clothes to dry without any air movement depends on various factors such as the fabric type, humidity levels, and temperature. On average, it can take anywhere from 24 to 48 hours for clothes to dry without any air movement.

3. Will clothes dry faster if there is air movement?

Yes, clothes will dry faster if there is air movement. Air movement helps to evaporate the moisture from the clothes, making them dry faster. This is why hanging clothes outside on a windy day will result in faster drying compared to hanging them inside a room with no air movement.

4. What is the best way to dry clothes without air movement?

The best way to dry clothes without air movement is to hang them in a well-ventilated area with low humidity levels. It is also helpful to choose a warm and sunny day for drying clothes without air movement, as the heat from the sun will help to evaporate the moisture from the clothes.

5. Are there any potential risks of drying clothes without air movement?

Yes, there are potential risks of drying clothes without air movement, such as the growth of mold and mildew on the clothes if they are not completely dried. It is important to make sure that the clothes are completely dry before storing them to avoid any potential risks.
