One mole of an ideal monoatomic gas is taken round the cyclic process MNOM. The work done by the gas is
- A \(4.5 p_0 V_0\)
- B \(4 p_0 V_0\)
- C \(9 p_0 V_0\)
- D \(2 p_0 V_0\)
Answer & Solution
Correct Answer
(D) \(2 p_0 V_0\)
Step-by-step Solution
Detailed explanation
Work done in cyclic process,
\(W=\) Area enclosed in cyclic process
\(=\frac{1}{2} \times O N \times O M\)
\(=\frac{1}{2} \times\left(3 V_0-V_0\right) \times\left(3 p_0-p_0\right)\)
\(=V_0 \times 2 p_0=2 p_0 V_0\)
\(W=\) Area enclosed in cyclic process
\(=\frac{1}{2} \times O N \times O M\)
\(=\frac{1}{2} \times\left(3 V_0-V_0\right) \times\left(3 p_0-p_0\right)\)
\(=V_0 \times 2 p_0=2 p_0 V_0\)
