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:

“A little water clears us of this deed.
How easy is it then!”
—William Shakespeare (1564–1616)

“It may be that through habit these do best,
Coming to water clumsily undressed
Yearly; teaching their children by a sort
Of clowning; helping the old, too, as they ought.”
—Philip Larkin (1922–1986)

“Rock of ages, cleft for me,
Let me hide myself in thee!
Let the water and the blood,
From thy riven side which flowed,
Be of sin the double cure;
Cleanse me from its guilt and pow’r.”
—Augustus Montague Toplady (1740–1778)
