Water is a chemical substance with the chemical formula H2O. A water molecule contains one oxygen and two hydrogen atoms connected by covalent bonds. Water is a liquid at temperatures above 0 °C (273.15 K, 32 °F) at sea level, but it often co-exists on Earth with its solid state, ice, and gaseous state (water vapor or steam). Water also exists in a liquid crystal state near hydrophilic surfaces.

Famous quotes containing the word water:
“Lord, crack their teeth! Lord, crush these lions jaws!
So let them sink as water in the sand;
When deadly bow their aiming fury draws,
Shiver the shaft ere past the shooters hand.
So make them melt as the dishoused snail”

“The tower nearest the water gets the moonlight first.”
“Over the water come
Children from homes and childrens parks
Who speak on a finger and thumb,
And the masked, headless boy.”
—Dylan Thomas (19141953)
