Gases - Molar Specific Heat

Molar specific heats of gases at constant volume

Approximate molar specific heats at constant volume at room temperature for some common gases:

GasSpecific Heat
- Cv -
(kcal/kmole K)
Argon (Ar) 3.0
Carbon monoxide (CO) 5.02
Chlorine (Cl2) 6.01
Ethane (C2H6) 10.3
Ether ((C2H5)2O) 30.8
Helium (He) 3.02
Hydrogen (H2) 4.88
Mercury vapor (Hg) 3.0
Nitrogen (N2) 6.97
Oxygen (O2) 4.99
Sulfur dioxide (SO2) 7.5
  • 1 kcal = 4186.8 J = 426.9 kp m = 1.163x10-3 kWh = 3.088 ft lbf = 3.9683 Btu = 1000 cal
