why the water goes up if I hold a paper towel up but touching it on a plate? What force is pushing/pulling the water against gravity?
In: Physics
It’s called capillary action. It takes advantage of two properties of water– Cohesion: water likes to stick to itself. Adhesion: water likes to stick to other things like paper towel fibers. These two things work together to overcome the force of gravity and bring the water upward through the tiny gaps between the fibers.
