WebCohesion is the ability of water molecules to bind together; this experiment ties into cohesion because for the water to stay on the penny, they must bind together. Hypothesis: I believe that about 15 water droplets will fit onto a penny. A droplet of water is rather small and water droplets will bind together. WebNov 18, 2010 · Drops On A Penny Lab Cohesion Water molecules are attracted to other water molecules. The oxygen end of water has a negative charge and the hydrogen end has a positive charge. The hydrogens of one water molecule are attracted to the oxygen from other water molecules. This attractive force is what gives water its cohesive properties. WebCohesion is the molecular force between particles within a body or substance that acts to unite them. Cohesion is in easier terms the bubble on top of the water you are pouring or the skin.
