Specific Heats of Gases - Cp, Cv, γ & Mayer's Relation

For ideal non-rigid diatomic gas, the value of RCV\frac{R}{C_V} is nearly (γ=CPCV=97)\left(\gamma = \frac{C_P}{C_V} = \frac{9}{7}\right)

Show answer and solution

Answer: (c)

  1. Cv=Rγ−1=R2/7=72RC_v = \frac{R}{\gamma-1} = \frac{R}{2/7} = \frac{7}{2}R
  2. RCv=27≈0.286\frac{R}{C_v} = \frac{2}{7} \approx 0.286
  3. So the answer is (c) 0.28.
