Ice Ic is a metastable cubic crystalline variant of ice. Metastability is a general scientific concept which describes states of delicate equilibrium The cubic crystal system (or isometric) is a Crystal system where the Unit cell is in the shape of a Cube. In Materials science, a crystal is a Solid in which the constituent Atoms Molecules or Ions are packed in a regularly ordered repeating Ice is a Solid phase, usually crystalline, of a Non-metalic substance that is liquid or gas at Room temperature, such as Ammonia The oxygen atoms are arranged in a diamond structure. Oxygen (from the Greek roots ὀξύς (oxys (acid literally "sharp" from the taste of acids and -γενής (-genēs (producer literally begetteris the It is produced at temperatures between 130-150 K, and is stable for up to 200 K, when it transforms into ice Ih. Ice Ih is the hexagonal crystal form of ordinary Ice, or frozen water. It is occasionally present in the upper atmosphere.
Ordinary water ice is known as ice Ih, (in the Bridgman nomenclature). Percy Williams Bridgman ( April 21, 1882 &ndash August 20, 1961) was an American physicist who won the 1946 Nobel Prize in Physics Different types of ice, from ice II to ice XIV, have been created in the laboratory at different temperatures and pressures.
