1. Introduction.

Water, you have no color, no taste, no smell,
you can not describe, you enjoy,
not knowing what you are. Can not say
that is necessary for life, you life itself.
You fills us with joy,
which can not be explained by our senses.
Are you coming back to us strength,
with whom we have already said goodbye.
By your grace in us again begin
bubbling springs dried up our hearts.
(Antoine de Saint-Exupery. Terre des Hommes)

I write a paper on the theme "Water - the most amazing stuff in the world." I chose this topic because - this is the most topical issue, since water is the most important substance on earth, without which there can be no one living organism and can not take place nor any biological, chemical reactions and processes.
Water - one of the most common materials in nature (hydrosphere takes 71% of the surface of the Earth). Water has a major role in the geology, history of the planet. Without water is impossible the existence of living organisms. The fact that the human body is almost 63% - 68% of water. Almost all biochemical reactions in every living cell - is a reaction in aqueous solutions ... In the (mostly water) flows most of the technological processes in the chemical industry, in the production of medicines and foods. And water industry is extremely important, not only for cooling. It is no accident hydrometallurgy - extraction of metals from ores and concentrates, with solutions of various reagents - has become an important industry.
