For polyatomic gases, the ratio of molar specific heat at constant pressure to constant volume is ( f = degrees of freedom )

Options

  1. A2+ f 3+ f
  2. B3+ f 2+ f
  3. C3+ f 4+ f
  4. D4+f 3+f

Correct answer

D. 4+f 3+f

Step-by-step solution

For polyatomic gases, molar-specific heat at constant volume is C _ V =(3+ f ) R and Molar-specific heat at constant pressure is C _ P =(4+ f ) R C _ P C _ V = 4+ f 3+ f
