Specific heat of Carbon Dioxide gas - CO2 - temperatures ranging 175 - 6000 K.
Carbon dioxide gas is colorless and heavier than air and has a slightly irritating odor. The freezing point is -78.5 oC (-109.3 oF) where it forms carbon dioxide snow or dry ice.
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 assimilated by plants and used to produce oxygen.
Carbon dioxide is at a low concentration in the atmosphere and acts as a greenhouse gas.
Specific heat (C) is the amount of heat required to change the temperature of a mass unit of a substance by one degree.
- Isobaric specific heat (Cp) is used for substances in a constant pressure (ΔP = 0) system.
- Isochoric specific heat (Cv) is used for substances in a constant-volume, (= isovolumetric or isometric) closed system.
The specific heat - CP and CV - will vary with temperature. When calculating mass and volume flow of a substance in heated or cooled systems with high accuracy - the specific heat should be corrected according values in the table below.
Specific heat of Carbon Dioxide gas - CO2 - at temperatures ranging 175 - 6000 K:

- cp -
The values above apply to undissociated states. At high temperatures above 1500 K (3223 oF) dissociation becomes appreciable and pressure is a significant variable.
