The work done by a gas as it is taken in a cyclic process (shown in graph) is
- A 2 pv
- B \(-2 \mathrm{pv}\)
- C \(3 \mathrm{pv}\)
- D \(-3 \mathrm{pv}\)
Answer & Solution
Correct Answer
(B) \(-2 \mathrm{pv}\)
Step-by-step Solution
Detailed explanation
\( \text{Area} = \frac{1}{2} \times \text{base} \times \text{height} \) \( \text{Base} = 3V - V = 2V \)
