Carbon dioxide
Carbon dioxide is a colourless and odourless gas condensed to a liquid. The gas is inert, non-combustible and oxygen suppressing. It is heavier than air.
The most known application of carbon dioxide is as sparkling means in soft drinks and beer. It is frequently used in conservatory cultivation and slaughterhouses. When packing nutrition carbon dioxide is also used, whether or not mixed with nitrogen. A not insignificant application of carbon dioxide is the use of it with fire-fighting equipment (fire extinguishers). Carbon dioxide also prevents the development of bacteria and is used for the control of the pH of waste water and swimming pools.
Physicochemical constants
| Symbol | CO2 |
|---|---|
| Average molecular weight (kg/mol) | 44.01 |
| Density of the gas (kg/m3 at 1.013 bar and 0 °C) | 1.977 |
| Relative density of the gas (air=1) | 1.53 |
| Sublimation point | - 78.5 °C (194.7 K) |
| Critical temperature | t = 31 °C (304.2 K), p = 73.8 bar |
