What will be the molar specific heat at constant volume of an ideal gas consisting of rigid diatomic molecules?

Answer»

`(3)/(2)R`
`(5)/(2)R`
R
`3R`

SOLUTION :For a diatomic GAS, there are five degrees of freedom: three translational and two rotational.
`therefore` Total energy of MOLECULE of one mole of a diatomic gas will be
`C_(V)=(dU)/(dT)=(d)/(dT)((5)/(2)RT)=(5)/(2)R`
