The subject of our video is water, but more specifically, the 7 different properties of water caused by hydrogen bonds. First, we describe why water is such a good solvent and use Airborne as an example. Next, we discuss the high specific heat of water, with boiling water as an example. Cohesion and adhesion are another property of water due to hydrogen bonds. Cohesion occurs because the negative oxygen molecules are attracted to the slightly positive hydrogen molecules. Adhesion means the molecules stick to other surfaces. Surface tension can be seen when water beads up on the surface of a leaf. Next, we talk about the reasons for variable pH of water. Dissociation is when a water molecule splits apart into smaller atoms due to the forces of adjacent hydrogen bonds. Last, we discuss the three different physical states of water: liquid, solid, and gas.
