The correct relation between the degrees of freedom f and the ratio...

The correct relation between the degrees of freedom ff and the ratio of specific heat γ\gamma is:

Options

  1. Af=2γ−1f = \dfrac{2}{\gamma - 1}
  2. Bf=2γ+1f = \dfrac{2}{\gamma + 1}
  3. Cf=γ+12f = \dfrac{\gamma + 1}{2}
  4. Df=1γ+1f = \dfrac{1}{\gamma + 1}

Correct answer

A. f=2γ−1f = \dfrac{2}{\gamma - 1}

Step-by-step solution

γ=1+2f\gamma = 1 + \dfrac{2}{f}

f=2γ−1f = \dfrac{2}{\gamma - 1}
