An ideal monoatomic gas is taken around the cycle \(A B C D A\) as shown in the \(p-V\) diagram. The work done during the cycle is given by
- A \(\frac{1}{2} p V\)
- B \(p V\)
- C \(2 p V\)
- D \(4 p \mathrm{~V}\)
Answer & Solution
Correct Answer
(B) \(p V\)
Step-by-step Solution
Detailed explanation
Work done in a cyclic process is equal to the area enclosed by the cycle in \(p-V\) diagram. \(\begin{aligned} \therefore \quad W &=\text { Area } A B C D \\ &=A B \times A D \\ &=(2 p-p) \times(2 V-V)=p \times V=p V \end{aligned}\)
