and are specific heats at constant pressure and constant volume respectively. It is observed that
for hydrogen gas
for nitrogen gas
The correct relation between a and b is :
As we learnt in
Specific heat capacity at constant pressure -
- wherein
f = degree of freedom
R= Universal gas constant
Cp - Cv = a (for hydrogen gas)
Cp - Cv = b (for nitrogen gas)
Cp - Cv = R ( Cp & Cv is molar specific heat)
If we convert molar specific heat to specific heat
a = 14 b
Since mass of 1 mole of H2 = 2 g/mole
mass of 1 mole of N2 = 28 gm/mole
