  WATER
Everything from the role of the waters of hydration in antibody-binding to the effect of solvation for stabilizing protein structure to the dependence of water's dielectric and pH on temperature and pressure.

  Water - Wikipedia, the free encyclopedia
Water (in its pure form) is a tasteless, odorless substance that is essential to all known forms of life and is known as the universal solvent.
Water is also used in industrial contexts, as a coolant during metallurgy, and in almost all powerstations as a coolant and to drive steam turbines to generate electricty.
Polluting water may be the biggest single misuse of water; to the extent that a pollutant limits other uses of the water, it becomes a waste of the resource, regardless of benefits to the polluter.

 Water (molecule) - Wikipedia, the free encyclopedia
Water is also used in many industrial processes and machines, such as the steam turbine and heat exchanger, in addition to its use as a chemical solvent.
Water chilled at the surface increases in density and sinks, forming convection currents that cool the whole water body, but when the temperature of the lake water reaches 4 °C, water on the surface decreases in density as it chills further and remains as a surface layer which eventually freezes and forms ice.
Hence, in ocean water, because of the salt content, the downward convection of colder water is not blocked by an expansion of water as it becomes colder near the freezing point; thus the oceans' cold water near the freezing point continues to sink.

 Water (2005)   (Site not responding. Last check: )
Baran was later thematically pilfered by a less successful film, Osama, which dealt with the harsh reality of an anti-feminist Taliban in Afghanistan, where a girl is caught pretending to be a boy by the Taliban regime, and the horrible consequences of her actions - only committed for the purpose of survival.
Water is similar to both of these films on several thematic levels.
Water, like Baran, is subtle, preferring to let the human side of the story tell you what you need to know, and showing us the necessity for change, for hope, for unbroken faith, without holding our hands through the process.

Distilled water, being essentially mineral-free, is very aggressive in that it tends to dissolve substances with which it is in contact due to its acidic properties.
Water filtered through a good reverse osmosis system tends to be neutral to slightly alkaline and is recommended for regular use provided that minerals are supplemented with vegetables or nutritional supplementation.
