Super Water! (Properties of Water)
By Trista L. Pollard |
|
1 Look on the ground! It's a liquid! It's an Earth material! It's water! Water, the most important substance on Earth, has many observable properties that make it one of the most amazing liquids known to mankind. Nothing on Earth can live without water. It is not only an essential nutrient, but it also serves as the vehicle by which our bodies receive important vitamins and minerals. Solid nutrients are not easily utilized by the body; however, when dissolved into water, they become part of a liquid solution that the body can readily use. Since water dissolves certain substances so well, pure water exists very rarely in nature. Most natural water carries dissolved minerals. Because so many substances will dissolve in water, water is often called a universal solvent. While it is true that water is an excellent solvent, it is not truly a universal solvent. There are many substances, particularly fats and oils, that will not dissolve in water. Water is also the only material that is found naturally on the Earth's surface in all three states of matter: liquid, solid, and gas. Ice is solid water. Water vapor is a gas. Let's take a look at water's many properties. |
