Have you ever filled a glass of water to the very top and then slowly added a few more drops? A water drop is composed of water molecules that like to stick together-an example of the property of cohesion. Adhesion allows for water to move against gravity through plant cells. What is adhesion and give an example? When you drop a small scrap of paper onto a droplet of water, the paper floats on top of the water droplet, although the object is denser (heavier) than the water. These properties are determined by the following molecular forces:The chemical bonds within the adhesive polymers;The chemical bonds resulting from crosslinking of the polymer;The intermolecular interactions between the molecules in the adhesive;The mechanical adhesion between various molecules in the adhesive. This process results in the release of individual water molecules at the surface of the liquid (such as a body of water, the leaves of a plant, or the skin of an organism) in a process called evaporation. They have grooves, bumps and notches caused by production itself, or by washing it, or by entering in contact with other tableware, whatever these imperfections plus adhesion are what makes the droplets that we see possible.
