dry ice:

see carbon dioxidecarbon dioxide,
chemical compound, CO2, a colorless, odorless, tasteless gas that is about one and one-half times as dense as air under ordinary conditions of temperature and pressure. It does not burn, and under normal conditions it is stable, inert and nontoxic.

Dry Ice


solidified carbon dioxide (CO2). Under ordinary conditions of atmospheric pressure and room temperature, dry ice changes directly to a gas, bypassing the liquid phase. Its name derives from its physical resemblance to ice. Industrial-grade dry ice has a density of approximately 1,560 km/m3 and absorbs approximately 590 kilojoules/kg (140 kilocalories/kg) during sublimation.

Dry ice is used to refrigerate food products, for example, ice cream, during shipment and storage. It is also used in producing low temperatures (approximately –79°C) in scientific research and in assembling and testing certain units in machine building.
