Nitrogen Gas - Specific Heat vs. Temperature

Specific heat of Nitrogen Gas - N2 - at temperatures ranging 175 - 6000 K

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.
  • I sochoric 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 (= heat capacity) should be corrected according values in the table below.

Nitrogen accounts for 78 % of the atmospheric air volume. Nitrogen is an inert, neutral and colorless gas.

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