One mole of an ideal gas is taken through an adiabatic process where the temperature rises from 27… C to 37… C. If the ideal gas is composed of polyatomic molecule that has 4 vibrational modes, which of the following is true? [R = 8.314 J mol^…1 k^…1]

Option B. Since, each vibrational mode, corresponds to two degrees of freedom, hence, f = 3 (trans.) + 3 (rot.) + 4 … 2 (vib.) = 14
