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:

    For months it hasn’t known the taste of steel
    Washed down with rusty water in a tin.
    But standing outdoors hungry, in the cold,
    Except in towns at night, is not a sin.
    Robert Frost (1874–1963)

    With a tongue like a razor he will kiss,
    the mother, the child,
    and we three will color the stars black
    in memory of his mother
    who kept him chained to the food tree
    or turned him on and off like a water faucet....
    Anne Sexton (1928–1974)

    The water for which we may have to look
    In summertime with a witching wand,
    In every wheelrut’s now a brook,
    In every print of a hoof a pond.
    Robert Frost (1874–1963)
