Water
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:
“We were uncertain whether the water floated the land, or the land held the water in its bosom. It was such a season, in short, as that in which one of our Concord poets sailed on its stream, and sung its quiet glories.”
—Henry David Thoreau (1817–1862)
“—the main jet
Struggling aloft unti it seems at rest
In the act of rising, until
The very wish of water is reversed,”
—Richard Wilbur (b. 1921)
“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 shooter’s hand.
So make them melt as the dishoused snail”
—Bible: Hebrew Psalm LVIII (Paraphrased by the Countess of Pembroke)
