Question

A thermodynamic system undergoes cyclic process ABCDA as shown in figure. The work done by the system in the cycle is (A) P0V0  (B) 2P0V0  (C)  (P0V0/2)  (D) zero

Work done in process ODA =1 / 2 × P o × V o While work done in the process OBC =(-1/2) P o V o ∴ net W =0

Q. A thermodynamic system undergoes cyclic process $A BC D A$ as shown in figure. The work done by the system in the cycle is

$P_{0} V_{0}$

$2 P_{0} V_{0}$

$\frac{P _{0} V _{0}}{2}$

zero

Work done in process $O D A = 1/2 \times P_{o} \times V_{o}$
While work done in the process $OBC = \frac{- 1}{2} P_{o} V_{o}$
$∴$ net $W = 0$
