Liquid carbon dioxide is a colorless gas with slightly sour taste, incombustible, easily dissolved in water. It is stored liquefied under pressure. Under atmospheric pressure it is turned into snow and gas in equal proportions at -78°C, produced by chemical industry or from natural sources, stored in containers under pressure at -20°C.
