Carbon Dioxide (CO2) is a colorless, odorless and nonflammable gas heavier than air. It is classified as one of the major air pollutants when it exceeds its naturally-occurring concentration. There are a number of processes for its production including combustion, fermentation and heating of organic matter. Its main use is in the food and beverage industry, although it is also used as a refrigerant, in fire extinguishing equipment, as a pressure source, aerosol propellant, and also in welding and some metallurgical processes.
Below are some of its major physical characteristics:
| Molecular weight: 44.0098 | Critical temperature: 304.21K |
| Melting point: 216.5K | Critical pressure: 7.3825MPa |
| Normal boiling point: 194.67K | Critical density: 466 kg/m3 |
| Normal vapor density: 1.98 kg/m3 | (@ 273.15K; 1.0135MPa) |
