Question

1. The adiabatic constant for polyatonic molecules
having f vibrational modes is​

Answer 1

Explanation:

f+4/f+3 hope u got the answer

Answer 2

The adiabatic constant for polyatomic molecules having f vibrational modes is​ $\frac{4+f}{3+f}$.

• The heat capacity ratio in thermal physics and thermodynamics, is the ratio of heat capacity at constant pressure to heat capacity at constant volume.
• For a polyatomic molecule with vibrational mode f ;

        U = (3+f) RT

        Cv = (3+f) R

        Cp = (4+f)R

• Thus, the ratio of $\frac{Cp}{Cv}$ = $\frac{4+f}{3+f}$.
