answer and explain appropriately
As you may know, liquid water boils and forms water vapor when its temperature is high enough to break the intermolecular bonds holding the water molecules together. However, even when the water's temperature is below the boiling point, some of the water molecules in the liquid break off into the air and become water vapor. How is this possible? The key is that not every water molecule in liquid water has the same energy. The temperature of a cup of liquid water does not tell us the exact energy of every single molecule. Rather, the temperature gives us an idea of theaverageenergy of all of the molecules. Because of the random, jostling nature of thermal motion, some molecules in a cup of water end up with far more energy than the average, and some molecules end up with less energy than the average. The molecules with more energy than the average often have enough energy to break free of their liquid-state intermolecular bonds and shoot off into the freedom of air. In this way, some amount of water molecules will always evaporate from the surface of liquid water, no matter the temperature of the liquid water. 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.
Water molecules on the surface of liquid water are evaporating into air at the same time that water molecules in the air are condensing onto the liquid water. In order for the liquid water to completely evaporate away, thus leaving the clothes dry, water molecules must leave the surface more quickly than they return.

Now let's apply these concepts to our wet clothes. There are two common things which can warm up the hanging clothes and thus make them dry quicker: ambient hot air, and light. All else being equally, wet clothes hanging on a hot day will dry much quicker than wet clothes hanging on a cold day. Similarly, all else being equal, wet clothes hanging in the sunlight will dry much quicker than wet clothes hanging in the dark.
2. Concentration of Water Molecules in the Surrounding Air.
Now the story gets more complicated. Not only do water molecules leave the surface of the liquid water and shoot off into air, water molecules that are in the air also bump into the liquid water and stick there
