All living organisms need Water
Water is a transparent liquid that makes the world’s oceans, lakes, rivers, streams, rain and the main ingredient fluids of organisms. Chemical formula is H2O. Water molecule contains one oxygen atom and two hydrogen atoms which are linked by covalent bonds. It is a liquid at standard temperature and pressure. It co-exists on the Planet Earth in it’s solid form as ice or gaseous form as vapor. There is a cloud, snow, hoar, fog and dew. Under the influence of solar radiation surface water continuously evaporates into the atmosphere (the water cycle). There it condenses (creating a rainy or snowy clouds in the atmosphere) in the form of precipitation (rain, snow, hail, dew, frost and fog). Then it returns to Earth, transferring such a large mass on the continents. We call it global hydrological cycle, so in many ways influences on the climate. At atmospheric pressure and a temperature between 0 ° C (when freezing) and 100 ° C (when boiling), pure or distilled is a color...
