Methane Gas - Specific Heat vs. Temperature

Specific heat of Methane Gas - CH4 - at temperatures ranging 200 - 1100 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 (C_p ) is used for substances in a constant pressure (ΔP = 0) system.
I sochoric specific heat (C_v ) is used for substances in a constant-volume , (= isovolumetric or isometric ) closed system.

The specific heat - C_P and C_V - 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.

Methane is a colorless, odorless gas with a wide distribution in nature. It is the principal component of natural gas, a mixture containing about 75% CH4, 15% ethane (C₂H₆ ), and 5% other hydrocarbons, such as propane (C₃ H ₈ ) and butane (C ₄ H ₁₀ ).
