Question

For an ideal gas undergoing an adiabatic process where $PV^{\gamma} = \text{const}$ and $\gamma = \frac{5}{3}$, the work done when volume changes from $V_1$ to $2V_1$ is:

Options

  1. A

    $\frac{P_1 V_1 \left(1 - 2^{-2/3}\right)}{\frac{2}{3}}$

  2. B

    $\frac{3P_1 V_1}{2}\left(1 - 2^{-2/3}\right)$

  3. C

    $P_1 V_1 \ln 2$

  4. D

    $\frac{2P_1 V_1}{\gamma - 1}$
