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:

    Milton says, that the lyric poet may drink wine and live generously, but the epic poet, he who shall sing of the gods, and their descent unto men, must drink water out of a wooden bowl. For poetry is not “Devil’s wine,” but God’s wine.
    Ralph Waldo Emerson (1803–1882)

    Beauclerc: You’ve got a good memory for one who drinks.
    Eddie: Drinkin’ don’t bother my memory. If it did, I wouldn’t drink. I couldn’t. You see, I’d forget how good it was. Then where’d I be? I’d start drinkin’ water again.
    Jules Furthman (1888–1960)

    Cities give not the human senses room enough. We go out daily and nightly to feed the eyes on the horizon, and require so much scope, just as we need water for our bath.
    Ralph Waldo Emerson (1803–1882)
