An ideal gas undergoes a process maintaining the relation between pressure $(P)$ and volume $(V)$ as $P = P_o(1 + (\frac{V_o}{V})^2)^{-1}$, where $P_o$ and $V_o$ are constants. If two samples $A$ and $B$ (two moles each) with initial volumes $V_o$ and $3V_o$ respectively undergo the above-mentioned process, calculate the difference in the temperatures of these samples, $T_B - T_A$, assuming the process is evaluated at their initial states. ($R$ = gas constant)

  • A
    $\frac{9P_o V_o}{8R}$
  • B
    $\frac{11P_o V_o}{10R}$
  • C
    $\frac{7P_o V_o}{6R}$
  • D
    $\frac{13P_o V_o}{11R}$
