Oxygen Gas - Specific Heat vs. Temperature
Specific heat of Oxygen Gas - O2 - 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.
- 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 (= heat capacity) should be corrected according values in the table below.
