carbon dioxide: Carbon dioxide is a gas. It is produced by animals and people breathing out, and by chemical reactions. A colorless, odorless, incombustible gas, CO, formed during respiration, combustion, and organic decomposition and used in food refrigeration, carbonated beverages, inert atmospheres, fire extinguishers, and aerosols. Also called carbonic acid gas. the gas produced when animals breathe out, when carbon is burned in air, or when animal or vegetable substances decay. Inorganic compound, a colourless gas with a faint, sharp odour and a sour taste when dissolved in water, chemical formula CO2. Constituting about 0.03% of air by volume, it is produced when carbon-containing materials burn completely, and it is a product of fermentation and animal respiration. Plants use CO2 in photosynthesis to make carbohydrates. CO2 in Earth's atmosphere keeps some of the Sun's energy from radiating back into space (see greenhouse effect). In water, CO2 forms a solution of a weak acid, carbonic acid (H2CO3). The reaction of CO2 and ammonia is the first step in synthesizing urea. An important industrial material, CO2 is recovered from sources including flue gases, limekilns, and the process that prepares hydrogen for synthesis of ammonia. It is used as a refrigerant, a chemical intermediate, and an inert atmosphere; in fire extinguishers, foam rubber and plastics, carbonated beverages (see carbonation), and aerosol sprays; in water treatment, welding, and cloud seeding; and for promoting plant growth in greenhouses. Under pressure it becomes a liquid, the form most often used in industry. If the liquid is allowed to expand, it cools and partially freezes to the solid form, dry ice
carbon dioxide: a colourless, odorless, aned slightly acid-tasting gas molecule which consists of one atom of carbon and two atoms of oxygen (CO2) It is produced in a variety of ways: by combustion or oxidation of materials containing carbon, such as coal, wood, oil, or foods; by fermentation of sugars and by decompostion of carbonates under the influence of heat or acids Carbon dioxide is a vital source to the Greenhouse Effect There are small amounts of it in the atmosphere to keep reflected heat from escaping Humans have made buildings and machines that release CO2 into the air The CO2 count in the air has nearly doubled since the beginning of the industrial era Trees help remove CO2 from the air as a natural process, but as humans keep on cutting down trees, there will be fewer and fewer recycled molecules of CO2, causing more carbon dioxide to be in the air Large amounts of CO2 in the atmosphere causes more heat to be kept in, causing global warming

carbon dioxide: Carbon dioxide, a normal product of burning fuel, is non-toxic, but contributes to the greenhouse effect (global warming) All petroleum (hydrocarbon) fuels cause increased atmospheric carbon dioxide levels because they represent the combustion of fossilized carbon By contrast, using renewable fuels, such as ethanol, does not increase atmospheric carbon dioxide levels The carbon dioxide formed during combustion is balanced by that absorbed during the annual growth of plants used to produce ethanol
