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:

    Suddenly I saw the cold and rook-delighting heaven
    That seemed as though ice burned and was but the more ice,
    William Butler Yeats (1865–1939)

    “A tedious brief scene of young Pyramus
    And his love Thisbe, very tragical mirth”—

    That is hot ice and wondrous strange snow!

    People in Stamps used to say that the whites in our town were so prejudiced that a Negro couldn’t buy vanilla ice cream. Except on July Fourth. Other days he had to be satisfied with chocolate.
