Uses

  Water (CAS NO.7732-18-5) is essential for the survival of all known forms of life.
In catabolism, water is used to break bonds in order to generate smaller molecules. Water is also central to photosynthesis and respiration. Water (CAS NO.7732-18-5) is also central to acid-base neutrality and enzyme function.
For human uses:
1. Agriculture:
The most important use of water in agriculture is for an irrigation and irrigation is key component to produce enough food.
2. Water as a scientific standard
3. For drinking
4. As a dissolving agent or solvent:
Dissolving (or suspending) is used to wash everyday items such as the human body, clothes, floors, cars, food, and pets.
5. As a heat transfer fluid:
Water and steam are used as heat transfer fluids in diverse heat exchange systems, due to its availability and high heat capacity, both as a coolant and for heating.
6. Extinguishing fires:
Water has a high heat of vaporization and is relatively inert, which makes it a good fire extinguishing fluid.
7. Chemical uses:
Organic reactions are usually quenched with water or a water solution of a suitable acid, base or buffer. Water is generally effective in removing inorganic salts.
8. Recreation:
Humans use water for many recreational purposes, as well as for exercising and for sports.
9. Water industry:
The water industry provides drinking water and wastewater services to households and industry.
10. Industrial applications:
Water is used in power generation.
11. Food processing:
  Water plays many critical roles within the field of food science.

Specification

  Water is the chemical substance with chemical formula H2O: one molecule of water as two hydrogen atoms covalently bonded to a single oxygen atom. Water is a tasteless, odorless liquid at standard temperature and pressure. Water is a polar molecule, so it has a high surface tension.Water also has high adhesion properties because of its polar nature. Water is a very strong solvent and is often referred to as the universal solvent.The boiling point of water is related to the barometric pressure. For example, on the top of Mt. Everest water boils at about 68 °C (154 °F), compared to 100 °C (212 °F) at sea level. Water is miscible with many liquids, for example ethanol, in all proportions, forming a single homogeneous liquid.Water and most oils are immiscible usually forming layers according to increasing density from the top. As a gas, water vapor is completely miscible with air. Water forms an azeotrope with many other solvents. Water can be split by electrolysis into hydrogen and oxygen.
