# Gases - Molar Specific Heats

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

Gases - Molar Specific Heats
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
