Properties of Water
All life depends on water and it is the unique properties of water that allow life to exist on this planet. Most of the physical properties of water are unique. Water can exist in different forms such as vapour, liquid or solid. Water exists as u liquid for only a relatively few degrees. It is this small temperature range that is most suited to life as we know it
Water’s density as a solid is less than it is as a liquid. This unique property allows ice to float. Water freezes first on the surface where heat is lost by radiation and evaporation. Surface ice forms an insulating layer over water, and life can continue beneath it throughout the winter.
Water has the greatest ability to store heat of any liquid. This means it can absorb or release large amounts of heat without much change in its own temperature. For plants and animals living in water, temperatures change more slowly than on land.
Water is often called the “universal solvent” because it can easily dissolve most solids, liquids and gases. The world’s rivers move water over long distances transporting nutrients dissolved in it. Most aquatic organisms can survive in water only if it contains enough dissolved oxygen to satisfy their requirements.
Photosynthesis, the basis of most life, is a complex reaction involving carbon dioxide, water, chlorophyll, and light to form carbohydrates and oxygen. It can take place in water thanks to the dissolved carbon dioxide and water’s unique transparency.
