Liquid carbon dioxide: Liquid carbon dioxide

Molecular formula: CO2, density 1.101g/cm, (-37 ° C). Dry ice is solid carbon dioxide.

Carbon dioxide is not much in the air, but it has a great impact on life activities. Liquid carbon dioxide is a refrigerant that can be used to preserve food or artificial rainfall. It is also an industrial raw material that can be used to make soda ash, urea and soda. Carbon dioxide can also be used for fire extinguishing.
