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.

    Once it was a boat, quite wooden
    and with no business, no salt water under it
    and in need of some paint. It was no more
    than a group of boards. But you hoisted her, rigged her.
    She’s been elected.
    Anne Sexton (1928–1974)
