Worked practice questions

A diatomic ideal gas has $C_v = \tfrac{5}{2}R$. Its $C_p$ and ratio $\gamma$ are:

  1. $\tfrac{5}{2}R$ and $\gamma = 1$, equal $C_v$ and $C_p$
  2. $\tfrac{3}{2}R$ and $\gamma = 5/3$, monatomic values here
  3. $\tfrac{9}{2}R$ and $\gamma = 2$, doubling all values
  4. $\tfrac{7}{2}R$ and $\gamma = 7/5$, since $C_p = C_v + R$
Show answer and solution

Correct answer: D. $\tfrac{7}{2}R$ and $\gamma = 7/5$, since $C_p = C_v + R$

$C_p = C_v + R = \tfrac{7}{2}R$; $\gamma = C_p/C_v = 7/5$.
