Specific heat of Hydrogen Gas - H2 - at temperatures ranging 175 - 6000 K
Specific heat (or heat capacity) (C) is the amount of heat required to change the temperature of a mass unit of a substance by one degree.
- Isobaric heat capacity (Cp) is used for substances in a constant pressure (ΔP = 0) system.
- Isochoric heat capacity (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.
Hydrogen gas is colorless, highly flammable and very light. Hydrogen is the lightest and most abundant element in the universe.

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