Ice

Ice is water frozen into the solid state. It can appear transparent or opaque bluish-white color, depending on the presence of impurities or air inclusions. The addition of other materials such as soil may further alter the appearance.

Ice appears in nature in forms of snowflakes, hail, icicles, glaciers, pack ice, frost, and entire polar ice caps. It is an important component of the global climate, and plays an important role in the water cycle. Furthermore, ice has numerous cultural applications, from ice cooling of drinks to winter sports and the art of ice sculpting.

The molecules in solid ice may be arranged in different ways, called phases, depending on the temperature and pressure. Usually ice is the phase known as ice Ih, which is the most abundant of the varying solid phases on the Earth's surface. The most common phase transition to ice Ih occurs when liquid water is cooled below 0°C (273.15K, 32°F) at standard atmospheric pressure. It can also deposit from vapour with no intervening liquid phase, such as in the formation of frost.

The word is derived from Old English īs, which in turn stems from Proto-Germanic isaz.

Famous quotes containing the word ice:

    Goodness and evil never share the same road, just as ice and charcoal never share the same container.
    Chinese proverb.

    When the ice is covered with snow, I do not suspect the wealth under my feet; that there is as good as a mine under me wherever I go. How many pickerel are poised on easy fin fathoms below the loaded wain! The revolution of the seasons must be a curious phenomenon to them. At length the sun and wind brush aside their curtain, and they see the heavens again.
    Henry David Thoreau (1817–1862)

    A young person is a person with nothing to learn
    One who already knows that ice does not chill and fire does not burn . . .
    It knows it can spend six hours in the sun on its first
    day at the beach without ending up a skinless beet,
    And it knows it can walk barefoot through the barn
    without running a nail in its feet. . . .
    Meanwhile psychologists grow rich
    Writing that the young are ones’ should not
    undermine the self-confidence of which.
    Ogden Nash (1902–1971)
