How do clothes dry ?

Question

We say that water boils at 100 degrees but why do clothes dry when the temperature of the earth is lesser than that ? Give me a legible answer.

Answer 1

some molecules in the liquid phase change into gas, this happens continuously and the rate changes with the temperature. since the humidity in the air in contact with the wet cloth is less than 100% the amount of water changing from liquid to gas is greater the amount of water changing back to liquid, the result is the cloth loses water. if you live the cloth hanging at night, after a very humid day, the balance will change as air humidity reaches 100% and the cloth will become wet again

Answer 2

Whether water is a liquid or a vapor depends on the energy level of individual water molecules. When you hang up a wet cloth to dry, water molecules receiving enough energy from the air to break free of the surface tension of the remaining water can escape into the air and float away. This actually leaves the cloth slightly cooler allowing it to attract more heat. Wet one wrist and blow on both wrists. Which feels cooler? At the top of a jar of canned tomatoes there is a near-perfect vacuum containing only water vapor. The water molecules are all free at the liquid surface to enter or leave the vapor space or liquid and constantly do so. As the jar is heated, the rate of exchange increases increasing the vapor pressure. And at the boiling point the vapor pressure is the same as atmospheric pressure and about to boil (even forming vapor bubbles in the liquid). If you double up a towel to dry, many water molecules will evaporate from one fold and re-enter another fold as liquid water slowing down the drying process. Providing the maximum area for evaporation (spread out the towel) speeds up drying (giving bacteria less time to multiply!). If the relative humidity in the (bath?) room is 100%, the air is holding all the moisture it can and any water vapor that leaves the towel will be replaced with water vapor from the air (like the jar of tomatoes!). Therefore, the towel will dry faster if spread out in dry air. Of course that is exactly why people used to hang out clothes to dry on a clothesline on a sunny day. Now electric (gas) clothes dryers heat the air (reducing its relative humidity and supplying energy to water molecules for evaporation). Hope that helps a little.

Answer 3

although water boils at 100C, it can eveporate at a lower temerature. surface area, temperature, air movement and the dryness of the air all affect how fast evaporation occurs.

Energy is required for evaporation and the surface cools as a result. This is how sweating cools our body.

Answer 4

wator needs more heat colth are dryed from the sun the sun shoots rays of light that turn into heat witch dry it

Answer 5

heat went thought de shirt then water in it vapourise
and turn into water vapour.... then slowly shirt is dry......
or can say than de atoms in de shirts(water) vibrates and lose forces of attraction and slowly turn into water vapour....but de water was evaporated instead of boils..... temp. in de air evaporate de most surface of de water on de shirt..... and therefore de water evaporate slowly.....

Answer 6

Heat, pressure or chemical...
