Carbon dioxide gaseous and liquid
The formula - CO2
Relative molecular weight (on the international nuclear weights of 1987) - 44,009
Carbon dioxide is issued as: gaseous, liquid low temperature and liquid high pressure. Carbon dioxide is applied to creation of the protective environment at welding of metals, in manufacture of the aerated drinks, an artificial ice, for cooling, freezing and storage of foodstuff, drying of foundry forms, fire fighting and other purposes of all industries.
Besides, the liquid dioxide of carbon is applied as the transportable form of dioxide of carbon which is used in a gaseous form for manufacture of artificial mineral waters, sparkling wines and other aerated drinks, and also for medical baths.
