Water

Introduction:

urine is the medium in which all the reactions rent place in living cellular phones such as respiration. invigoration cells ar made up of cytoplasm, nucleus, cell membrane and cell wall (in plants). Cytoplasm is 80% water. All known forms of life history depend on water. body of water is vital both as a solvent in which many of the bodys solutes dissolve and as an essential part of many metabolic processes within the body.
Water is needed for photosynthesis on which all type of life depends like a shot and indirectly. Water covers 70% of the planets surface and in addition supports more life than anywhere else on the planet earth.
chemistry of Water

The chemical formula of water is H2O. Two instalments of atomic number 1 liquefy with one atom of oxygen to make one jot of water.
Every water molecule is approximately polarised which means it has a very jolly negative part the oxygen atom and the slightly positive part the hydrogen atom. This difference in charge gives water its dipole constitution.
One of the most all-important(prenominal) outcomes of this charge difference is that the water molecules form hydrogen bonds. The slightly negative oxygen atom will attract slightly positive hydrogen atoms of some other water molecules. This bonding is called the hydrogen bonds.



Its is a very weak bond but considering a very large numbers of these hydrogen bonds between contrasting water molecules, it has a significant effect. Therefore, water molecules stick in concert more than we might otherwise expect. This leads to water having a comparatively high melting and boiling points because it takes more energy to strike the attractive forces off all the hydrogen bonds.

Following are the unique properties of water that supports life,

1. Water is an unusual and excellent solvent.

Water is a universal solvent because it dissolves more substances that any other liquids found on the surface of the earth. This is all because of the dipole (oppositely charged) nature of water. Since, water molecule is dipole means that many ionic...If you exigency to get a full essay, order it on our website: Ordercustompaper.com
