The ratio of specific heats C P C V in terms of degree of freedom f is given by :

Options

  1. A1 + f 3
  2. B1 + 2 f
  3. C1 + f 2
  4. D1 + 1 f

Correct answer

B. 1 + 2 f

Step-by-step solution

From Mayer's relation C P = C V + R and C V = f 2 R Ratio of specific heat, γ = C P C V = 1 + R f 2 R = 1 + 2 f
