An ideal gas has molecules with 55 degrees of freedom. The ratio of specific heats at constant pressure \left({C}_{p}\right)andatconstantvolume(CV)and at constant volume \left({C}_{V}\right) is:

Options

  1. A75\dfrac{7}{5}
  2. B66
  3. C72\dfrac{7}{2}
  4. D52\dfrac{5}{2}

Correct answer

A. 75\dfrac{7}{5}

Step-by-step solution

γ=CpCV=1+2f=1+25=75\gamma = \dfrac{Cp}{CV} = 1 + \dfrac{2}{f} =1 + \dfrac{2}{5}= \dfrac{7}{5}.
