This video demonstrates the five main properties of water. These include, but are not limited to, water's ability to cohere, adhere, create surface tension, have a high specific heat, and act as a solvent. In cohesion, hydrogen bonds found in the water molecules allow water to stick together via the bonds created when a hydrogen atom on one molecule connects to the oxygen atom on another. Adhesion is the water molecules ability to stick to other surfaces instead of just other water molecules. The combination of cohesion and adhesion allow water to move upwards, defying gravity. High specific heat is due to the water molecules variable lengths and weaknesses of hydrogen bonds, they break easily and are poor conductors of heat and energy. Waters ability to act as a solvent is another main property, the water molecules break down the solute, causing it to be distributed throughout the water. Lastly, in surface tension, water molecules connect to one another, causing them to become one. This allows for small objects and insects to graze water without falling through.
