The values above apply to undissociated states. At high temperatures above 1500 K dissociation becomes appreciable and pressure is a significant variable.

  • 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 -78.5 oC where it forms carbon dioxide snow or dry ice.
