Infinity Learn · Accepted Answer

$$CV=fR2$$,   $$CP=fR2+R$$ ⇒   $$CPCV=f+2f$$,  f    is degrees of freedom.

Match the $C_{P} / C_{V}$ ratio for ideal gases with different type of molecules :
Molecule Type $C_{P} / C_{V}$
(A) Monatomic (I) 7/5
(B) Diatomic rigid molecules (II) 9/7
(C) Diatomic non-rigid molecules (III) 4/3
(D) Triatomic rigid molecules (IV) 5/3
