How Does Water Move Through Paper? Paper is made of plant fibers. In the process of making paper, the fibers overlap forming a massive network of tunnels in all directions throughout the paper. The chemical molecules making up the fibers are attractive to water water molecules. Adhesion is the name of the force of [...]
Capillary Action is also called wicking, which is the ability of a substance to draw another substance into it. In the diagram, three different size glass tubes are standing in a container of colored water. Notice that the water rises to a different height in each of the tubes. The more narrow the tube, the [...]
Question: Why doesn’t water form bubbles? Answer: Cohesion is the force between molecules that are alike, such as between water molecules. The cohesion between water molecules too strong to allow the water to form bubbles. The bubbles shown in the photo are made with a solution of soap and water. The soap reduces the force [...]
