Ethylene 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 (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 figures and the table below.
Isobaric, CP, and isochoric, CV, specific heat of ethylene at gas-liquid equilibrium pressure and varying temperature, °C and °F:
Isobaric, CP, and isochoric, CV, specific heat of ethylene at atmospheric pressure and varying temperature, °C and °F:
