Description

Technical Field

[0002] Carbon dioxide is a colorless, tasteless and odorless gas at room temperature. Its chemical formula is CO2, and its formula weight is 44.01. It is one of the carbon oxides, commonly known as carbonic acid gas, also known as carbonic anhydride or carbonic anhydride. It is a colorless and tasteless gas at room temperature, with a density slightly greater than that of air. It dissolves in water (1 volume of H2O can dissolve 1 volume of CO2) and produces carbonic acid. Solid carbon dioxide is commonly known as dry ice, which can absorb a lot of heat when sublimated, so it is used as a refrigerant, such as artificial rainfall, and is also often used to make smog (dry ice sublimates and absorbs heat, liquefying water vapor in the air).
