ice

Solid form of liquid water and water vapour. Below 32 °F (0 °C), liquid water forms a hard solid and water vapour forms frost on surfaces and snowflakes (see snow) in clouds. Unlike most liquids, water expands on freezing, so ice is less dense than liquid water and therefore floats. It consists of compact aggregates of many crystals (with hexagonal symmetry), although ice formed from the bulk liquid does not normally have crystal faces. Molecules in the crystal are held together by hydrogen bonds (see hydrogen bonding). With a very high dielectric constant, ice conducts electricity much better than most nonmetallic crystals. At very high pressures, at least five other crystal forms of ice occur.

(1) (Information and Content Exchange) A data sharing specification that allows one Web site to obtain data from another Web site. Using meta tags, ICE provides a standard way of defining a company's data. ICE is based on XML and OPS. See XML, OPS and meta tag.

(2) (In-Circuit Emulator) A chip used for testing and debugging logic circuits typically in embedded systems. The chip emulates a particular microprocessor and contains breakpoints and other debugging functions. See ROM emulator.

(3) (In Case of Emergency) A cellphone entry stored under the name of "ICE" that contains an emergency contact number and other medical information. It was recommended by a British paramedic, and a campaign for public awareness was launched in the U.K. in 2005.

(4) (Ice) A Lotus 1-2-3 add-on from Baler Software Corporation, Rolling Meadows, IL, that added extensions to Lotus macros.
