Description
A colorless, odorless gas. Carbon dioxide is naturally produced as a byproduct of respiration, combustion, and decomposition. It has an abundance of 0.027-0.036% in earth's atmosphere. Carbon dioxide is used to make carbonated beverages, aerosol propellants, and fire extinguishers. In museums, it has also been used to create inert, oxygen-free environments to minimize oxidative degradation and to asphyxite insects. Solid carbon dioxide, Dry ice, is used for refrigeration and special effects. Liquid carbon dioxide, compressed at high pressures (see Supercritical fluid), has been used as a solvent to remove DDT from artifacts (Kang et al. 2004).
