dry ice
dry icen. Solid carbon dioxide that sublimates at -78.5°C (-110°F) and is used primarily as a coolant.
[Originally a trademark.]dry ice n (Elements & Compounds) solid carbon dioxide, which sublimes at –78.5°C: used as a refrigerant, and to create billows of smoke in stage shows. Also called: carbon dioxide snow dry′ ice′
n. the solid form of carbon dioxide, which sublimes at −109.26°F (−78.48°C) and is used chiefly as a refrigerant. dry ice Solid carbon dioxide. Dry ice evaporates without first passing through a liquid state, by a process known as sublimation. It is used for refrigeration. See Note at sublimation.Thesaurus| Noun | 1. | dry ice - solidified carbon dioxide; dry ice sublimates at -78.5 C and is used mainly as a refrigerantsolid - matter that is solid at room temperature and pressure |

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.

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. dry ice[¦drī ′īs] (inorganic chemistry) Carbon dioxide in the solid form, usually made in blocks to be used as a coolant; changes directly to a gas at -78.5°C as heat is absorbed. dry ice solid carbon dioxide, which sublimes at --78.5?C: used as a refrigerant, and to create billows of smoke in stage shows dry ice
carbon dioxide an odorless, colorless gas, CO2, resulting from oxidation of carbon, formed in the tissues and eliminated by the lungs; used in some pump oxygenators to maintain the carbon dioxide tension in the blood. It is also used in solid form; see carbon dioxide snow and carbon dioxide slush.carbon dioxide combining power the ability of blood plasma to combine with carbon dioxide; indicative of the alkali reserve and a measure of the acid-base balance of the blood.carbon dioxide content the amount of carbonic acid and bicarbonate in the blood; reported in millimoles per liter.carbon dioxide–oxygen therapy administration of a mixture of carbon dioxide and oxygen (commonly 5 per cent CO2 and 95 per cent O2 or 10 per cent CO2 and 90 per cent O2); used for improvement of cerebral blood flow, stimulation of deep breathing, or treatment of singultation (hiccupping). Carbon dioxide acts by stimulating the respiratory center; it also increases heart rate and blood pressure. Therapy is given for 6 minutes or less with a 5 per cent mixture and 2 minutes or less with a 10 per cent mixture. Potential adverse effects include headache, dizziness, dyspnea, nausea, tachycardia and high blood pressure, blurred vision, mental depression, coma, and convulsions.carbon dioxide slush solid carbon dioxide combined with a solvent such as acetone, and sometimes also alcohol; used as an escharotic to treat skin lesions such as warts and moles and as a peeling agent in chemabrasion.carbon dioxide snow the solid formed by rapid evaporation of liquid carbon dioxide, giving a temperature of about −79°C (−110°F). It has been used in cryotherapy to freeze the skin, thus producing local anesthesia and arrest of blood flow. See also carbon dioxide slush.car·bon di·ox·ide snowsolid carbon dioxide used in the treatment of warts, lupus, nevi, and other skin affections, and as a refrigerant.
