H2o definition & formula

What is H2O full form?
H 2 O is commonly known as water
...
It is dihydrogen monoxide which contains two moles of
hydrogen and one mole of oxygen
...


* water, a substance composed of the chemical elements hydrogen and oxygen and existing
in gaseous, liquid, and solid states
...

A tasteless and odourless liquid at room temperature, it has the important ability to dissolve
many other substances
...
Life is believed to have originated in the aqueous solutions of the world’s oceans,
and living organisms depend on aqueous solutions, such as blood and digestive juices, for
biological processes
...
In small quantities water appears colourless, but water actually has an
intrinsic blue colour caused by slight absorption of light at red wavelengths
...
For example, although the sight of ice cubes floating in a glass of
ice water is commonplace, such behaviour is unusual for chemical entities
...
The fact that ice floats on water is exceedingly important in the

natural world, because the ice that forms on ponds and lakes in cold areas of the world acts
as an insulating barrier that protects the aquatic life below
...
Thus, the pond would eventually freeze throughout, killing all the life-forms
present
...
The fact that water is readily changed to a vapour (gas) allows it to be transported
through the atmosphere from the oceans to inland areas where it condenses and, as rain,
nourishes plant and animal life
