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:
“The point of the dragonfly’s terrible lip, the giant water bug, birdsong, or the beautiful dazzle and flash of sunlighted minnows, is not that it all fits together like clockwork--for it doesn’t ... but that it all flows so freely wild, like the creek, that it all surges in such a free, finged tangle. Freedom is the world’s water and weather, the world’s nourishment freely given, its soil and sap: and the creator loves pizzazz.”
—Annie Dillard (b. 1945)
“I am no Poet here; my pen ‘s the spout,
Where the rain water of my eyes run out,
In pity of that name, whose fate wee see
Thus copied out in griefs Hydrography:
The Muses are not Mer-maids, though upon
His death the Ocean might turn Helicon”
—John Cleveland (1613–1658)
“You cannot go into the same water twice.”
—Plato (c. 427–347 B.C.)
