An ideal gas is taken via path \(A B C A\) as shown in figure.
The network done in the whole cycle is
- A \(3 p_{1} V_{1}\)
- B \(-3 p_{1} V_{1}\)
- C \(6 p_{1} V_{1}\)
- D Zero
Answer & Solution
Correct Answer
(B) \(-3 p_{1} V_{1}\)
Step-by-step Solution
Detailed explanation
Net work done in cyclic process \(A B C A\), \(W_{\text {net }}=\) Areu enclosed by path \(A B C A\) \[ \begin{aligned} &=\frac{1}{2} \times\left(3 V_{1}-V_{1}\right)\left(4 p_{1}-p_{1}\right) \\ &=\frac{1}{2} \times 2 V_{1} \times 3 p_{1}=3 p_{1} V_{1} \end{aligned} \] Since,…
