Carbon dioxide gas is produced from the combustion of coal or hydrocarbons or by fermentation of liquids and the breathing of humans and animals.
Carbon dioxide is at a low concentration in the atmosphere and acts as a greenhouse gas. Carbon dioxide is assimilated by plants and used to produce oxygen.
Carbon dioxide gas is colorless and heavier than air and has a slightly irritating odor.
Freezing point is -109.3 oF (-78.5 oC) where it forms carbon dioxide snow or dry ice.
