Q. An ideal 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) $p_{3} = p_{1},\ W = 0$
Explanation
The correct answer is Option B: $p_{3} > p_{1},\ W < 0$.
