For a diatomic gas, if ₁= ( C p C v ) for rigid molecules and ₂= ( C p C v ) for another diatomic molecules, but also having vibrational modes. Then, which one of the following options is correct ? (Cp and Cv are specific heats of the gas at constant pressure and volume)

Quantrex Academy · Accepted Answer

Correct answer: C. ₂ ₁

For rigid diatomic molecules array ll & f=5 & ₁= 7 5 =1.4 array For non-rigid diatomic molecules array ll & f=5+2=7 & ₂= 9 7 =1.28 & ₁> ₂ array
