How Water Is Made?

It is the simplest compound of oxygen and hydrogen being comprised of two molecules of hydrogen to one of oxygen. It is formed when an electric spark passes through a mixture of gases and is the product of the combustion of al hydrogen–containing compounds like: petrol, coal, gas and wood.
Water is essential to life. It is the medium which carries food to plants and animals. Pure water freezes at 0 degrees Celsius and boils at 100 degrees Celsius at sea level. This s a recognised standard of temperature on this scale. It has maximum density at four degrees Celsius.
Heating water above 100 C converts it to steam. This has been useful to drive all manner of engines – everything from railway engines to power stations.
Water is one of the few things which freezes from the surface down rather from the centre up. This has an important significance for life in rivers and lakes.

Water is made when numerous molecules are attracted to one another. Water is made up of hydrogen and oxygen. Water is a solvent liquid and it is capable of dissolving another substance. However, not all liquids are solvent. It is the loose and uneven structure of molecules in water that make it such a good solvent. Water can also change its structure easily when exposed to a certain temperature. It freezes or evaporates as its molecular structure changes. Water has a very high polarity. A polar molecule has positive as well as a negative region. This causes the molecule to become attracted to different types of molecules. This is the reason why water is liquid.

Water is formed when oxygen and hydrogen reacts together at a specific temperature and pressure.

2 H₂(g) + O₂(g) = 2 H₂O(g)

During the reaction 2 moles of hydrogen gas combine with one mole of oxygen gas to produce two moles of steam. Please view the diagram to see the chemical nature of bond formed between the two elements.
