Options

  1. AA-III, B-IV, C-I, D-II
  2. BA-III, B-II, C-IV, D-I
  3. CA-II, B-IV, C-I, D-III
  4. DA-IV, B-II, C-III, D-I

Correct answer

A. A-III, B-IV, C-I, D-II

Step-by-step solution

γ=1+2f\gamma=1+\frac{2}{\mathrm{f}}
f=6f=6, Triatomic rigid gas
f=7\mathrm{f}=7, Diatomic non-rigid gas
f=5f=5, Diatomic rigid gas
f=3\mathrm{f}=3, monoatomic rigid gas
γ=1+26=43\gamma=1+\frac{2}{6}=\frac{4}{3} (Triatomic)
γ=1+27=97(\gamma=1+\frac{2}{7}=\frac{9}{7}( Diatomic, non-rigid ))
γ=1+25=75(\gamma=1+\frac{2}{5}=\frac{7}{5}( Diatomic, rigid ))
γ=1+23=53(\gamma=1+\frac{2}{3}=\frac{5}{3}( Monoatomic, rigid ))
A-III, B-IV, C-I, D-II
