How do you I stop my TV from turning off at a time dish? Conversely, as molecular motion decreases and temperatures drop, less energy is present to break the hydrogen bonds between water molecules. Answer: Our bodies use water in all the cells, organs, and tissues, to help regulate body temperature and maintain other Water molecules have strong cohesive forces due to their ability to form hydrogen bonds with one another. Depending on the strength of these forces, the adhesion failure can be either adhesive, cohesive, or substrate failure. In cohesion, water molecules are attracted to each other (because of hydrogen bonding), keeping the molecules together at the liquid-air (gas) interface, although there is no more room in the glass. Evaporation of sweat, which is 90 percent water, allows for cooling of an organism, because breaking hydrogen bonds requires an input of energy and takes heat away from the body.
