An ideal gas expands isothermally from a volume $V_1$ to $V_2$ and then compressed to original volume $V_1$ adiabatically. Initial pressure is $P_1$ and final pressure is $P_3$. The total work done is $W$ . Then

A

$P_3 > P_1,\,W > 0$

B

$P_3 < P_1,\,W < 0$

C

$P_3 > P_1,\,W < 0$

D

$P_3 = P_1,\,W = 0$

Solution

$\mathrm{P}_{3}>\mathrm{P}_{1}$ and $\mathrm{W}<0$
