Biological Importance of Water

The Biological Importance of peeing Water is a silvery that is colorless, transp atomic number 18nt and odorless. It is one of the most important biologic systems and it has numerous unequalled properties that make it essential to all life. Water exists in nature in all three states of question (solid, liquid, gas), and it excessively covers 75% of the earth and composes roughly 78% of our body. some of irrigates unique properties are a result of the heat content bonds surrounded by irrigate jots. Structure of Water1.Hydrogen bonds because weewee supply molecules are diametric covalent molecules, it has a slight positive and slight contradict charge on opposite ends. Like the positive and disallow ends of a magnet, the water molecules are attracted to severally separate. Because of these attractive forces, water molecules are in close proximity to one another, devising water in truth dense. In addition, as a result of the attractive forces, the atomic number 8 and hydrogen atoms class hydrogen bonds. Since the oxygen atom has 2 pairs of nonbonding electrons, each oxygen in a single molecule nooky form H-bonds with two hydrogens. Figures on the next varlet scan such a hydrogen bond. The resulting clusters of molecules make water cohesive. In its liquid phase, H-bonds are distorted and the network of molecules is irregular.

When water freezes, the H-bonds form the water molecules into a regular latt nut case with more mode between the molecules than in liquid water; consequently ice is less dense than liquid water. 2. Water as a solventWater is a good solvent. As a polar covalent compound, water can dissolve ! many substances. It is in feature called ?the universal solvent?. Because polar covalent compounds provoke charged poles, they dissolve in water and so they are verbalize to be hydrophilic, which means ?water loving?. On the other hand, nonpolar covalent compounds do not dissolve... If you wishing to arrive at a full essay, order it on our website: OrderCustomPaper.com
