Water in the solid state; specif. the dense substance formed in nature by
the freezing of liquid water, by the condensation of water vapor directly
into ice crystals, or by the recrystallization or compaction of fallen
snow. It is colorless to pale blue or greenish blue, usually white from
included gas bubbles. At standard atmospheric pressure, it is formed at
and has a melting point of 0 degrees C; in freezing it expands about one
eleventh in volume. Ice commonly occurs in hexagonal crystals, and in
large masses is classed as a rock. AGI
