Document Summary
Water is an essential part of the process of earth. In this lab, i will investigate the properties of water and explain how they affect earth material and surface processes. Cohesion is the ability of molecules to bind together. One way to test this is by investigating how the droplets of a particular liquid stick together compared to other liquids. Using the materials i have i need to determine water"s relative cohesion on a particular surface. I will follow this plan by using my list of materials to complete this lab assignment. I have at least a whole day to complete this so it can be done right and not be rushed. Cohesive refers to the attraction of molecules for other molecules of the same kind, and water molecules have strong cohensive forces thanks to their abililty to form hydrogen bonds with one another. Surface tension is a property of a liquid that allows the surface to resist force.
