For example clothing on a washing line. How does it dry up? What makes the water get out of the clothes? Where does the water go?
Also a different question but still on the same topic; what is the reason that some materials such as glass don’t absorb water, but materials like paper do?

Heat is just a human concept for the kinetic motion of the molecules of an object. When you hear water up past 100C the molecules are moving so fast that they are not able to stay together and become vapor. However, when water is not that hot, *some* of the molecules of water *do* move fast enough to break free. You can see this when you leave an open container of water overnight and it evaporates slightly. The less humid the air surrounding the water is, the easier it is for that water to evaporate into the atmosphere and dry up the container or soaked object.
The reason paper soaks up water is because paper has microscopic spaces between each cellulose fiber that’s big enough for water to seep through. Glass has no pores that are big enough for water so it does not absorb water.
