WATER AN ELIXIR OF LIFE (A REVIEW)

Dr Sanjay Sharma

Abstract :

 Water can exist in all three states of matter solid, liquid and gas. Under ambient conditions it is liquid. Only 2.5% of the Earth‘s water is fresh water, and 98.8% of that water is in ice and groundwater. Less than 0.3% of all freshwater is in rivers, lakes, and the atmosphere, and an even smaller amount of the Earth‘s freshwater (0.003%) is contained within biological bodies and manufactured products. Water is most widely used chemical by all living beings, water has some unique properties , Life depends upon these unique properties of water ( Luck, 1985).Availability of water is one of the criterions used by Astronauts for searching existence of life on different planets. Water has large heat capacity, high thermal conductivity, high water content in organisms prevent local temperature fluctuations. Due to high latent heat of evaporation it is resistant to dehydration and considerable coolant. Water is an excellent solvent due to its polarity, high dielectric constant and small size, particularly for polar and ionic compounds and salts. Without water, biological processes particular metabolic processes could not exist.
