A polyatomic gas at pressure 'P', having volume 'V' expands isothermally to a volume ' 3 V ' and then adiabatically to a volume ' 24 V '. The final pressure of gas is (for moderate temperature changes)
- A 16 P
- B 24 P
- C \(\mathrm{P} / 36\)
- D \(\mathrm{P} / 48\)
Answer & Solution
Correct Answer
(D) \(\mathrm{P} / 48\)
Step-by-step Solution
Detailed explanation
\(P_1 V_1 = P_2 V_2\) \(P \cdot V = P' \cdot (3V) \implies P' = P/3\)
