Water is a substance composed of the chemical elements hydrogen and oxygen and existing in gaseous, liquid, and solid states. Water is one of the most plentiful and essential of compounds. It is vital to life, participating in virtually every process that occurs in plants and animals. Although the molecules of water are simple in structure, the physical and chemical properties of the compound are extraordinarily complicated. Water is a colourless, tasteless, and odorless liquid at room temperature. One of its most important properties is its ability to dissolve many other substances. The versatility of water as a solvent is essential to living organisms. Life is believed to have originated in the world's oceans, which are complicated solutions. Living organisms use aqueous solutions as mediums for carrying out biological processes. |
