Methane Gas - Specific Heat vs. Temperature
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 (C 2 H 6 ), and 5% other hydrocarbons, such as propane (C 3 H 8 ) and butane (C 4 H 10 ).
