	Ice - Wikipedia, the free encyclopedia
		When ice melts, it absorbs as much heat energy (the heat of fusion) as it would take to heat an equivalent mass of water by 80 °C, while its temperature remains a constant 0 °C. As a crystalline solid, ice is considered a mineral.
		Ice scrapers are tools designed to break the ice free and clear the windows, though removing the ice can be a long, labor-intensive, and stressful process—especially when a driver ends up running late for work as a result.
		It is troublesome to remove this form of ice, so people often open their windows slightly when the vehicle is parked in order to let the moisture dissipate, and it is now common for cars to have rear-window defrosters to combat the problem.

	Ice XII - Wikipedia, the free encyclopedia
		Ice XII is a metastable, dense, crystalline phase of solid water.
		It was first obtained by cooling liquid water to 260 K at a pressure of 0.55 GPa; it was discovered existing within the phase stability region of ice V.
		Pure ice XII can be created from high density amorphous ice (HDA) under high compression, 0.81-1.00 GPa/min, and temperatures below 77 K. It transforms at temperatures above 135 K to cubic ice (Ic).

		Ice, water and water vapour can coexist at the triple point, which for this system is 273.16 K at a pressure of 611.73 Pa.
		An unusual feature of ice frozen at a pressure of one atmosphere is that the solid is less dense than liquid water (10 % less).
		Ice is also a colloquial term for diamond, and also for some forms of the drug amphetamine.

		The first success has been ice XII, a totally new structure that we have found within the stability region of ice V and which was prepared by crystallisation from the liquid phase.
		At present, ice XII is the densest known phase of the water substance without interpenetration.
		First, the enhanced richness of the ice phase-diagram in the medium pressure range is an excellent demonstration of the versatility of the water molecule that enables the building of a variety of hydrogen-bonded structures sometimes in very close competition for occupying the same region of p-T space.

	Ice - the large food & drink encyclopedia
		The ice was brought in during the winters from nearby mountains in bulk amounts, and stored in specially designed, naturally cooled refrigerators, called yakh-chal (meaning ice storage).
		This was a large underground space (up to 5000 m³) that had thick walls (at least 2 meters at the base) made out of a special mortar called sarooj, that comprised of sand, clay, egg whites, lime, goat hair, and ash in specific proportions, and which was resistant to heat transfer.
		The ice was then used to feed royalty chilled treats during hot summer days.

		Ice VIII forms a tetragonal crystal containing eight water molecules per unit cell, where all of the water molecules are hydrogen bonded to four others, two as donor and two as acceptor.
		Ice XI Ice XI was initial observed by Kawada in 1972, however it took until 1984 when Tajima performed high precision calorimetry experiments for ice XI to be accepted as a new phase.
		Ice XII Ice XII may be formed by heating high-density amorphous ice at a constant pressure of 0.81 GPa from 77 K to ~183 K and recovered at atmospheric pressure at 77 K. Ice-twelve is metastable within the ice-five and ice-six phase space.

		Ice XII, therefore, is rather prolific in water's phase diagram existing in at least two topologically unconnected regions.
		The study of the formation of ice Ih to ice XII contributes valuable clues to the understanding of water amorphisation under pressure.
		Moreover, since the structure of ice XII has been established as the first example of a non-self-clathrating network built up by seven- and eight-membered rings of water molecules it may help us to deduce some structural characteristics for HDA.

		Snow accumulates, compresses to ice, and removes air bubbles, about 90% as dense as water.

		Glacier bed is often melted by the weight of overlying ice, providing lubrication to speed glacier flow.

		To date, they have developed 12 different types of ice, the most recent of which are ice XI and ice XII.
		Discovered by scientists at the Universite Montpellier II, ice XI is crystalline water subjected to 3-4 megabars of pressure at room temperature to form a dense crystal lattice having a hexagonal structure.
		Ice XII was formed by subjecting liquid water to an electric field to stimulate the formation of a quartz-like crystalline structure.

		This is a representation of the hexagonal arrangement of the ice structure, as seen down one axis of the crystal (the c axis).
		The water molecules in ice occupy a smaller fraction of the overall volume than they do in liquid water, which accounts for the large density difference between ice and water.
		This strucural form of ice is the only form known to occurs naturally on Earth and is known as ice I. Other structural forms are have been found experimentally and computationally and may exist in extreme environments such as near the base of the Antarctic ice cap or on Jupiter.
