The molar specific heat at constant pressure of an ideal gas is 7/2R. The gas is made up of molecules which are (a) polyatomic (b) non-rigid diatomic (c) rigid diamotic (d) monoatomic

Answer: (c). Cv = Cp - R = 7/2R - R = 5/2R. Cv = f/2R ⇒ f = 5: 3 translational + 2 rotational. So the answer is (c) rigid diatomic.
