A gas having \(\gamma=\frac{5}{2}\) and volume 360 c.c. is suddenly compressed to 90 c.c. If the initial pressure of the gas is P , then the final pressure will be
- A \(\frac{\mathbf{P}}{4}\)
- B 8 P
- C 16 P
- D 32 P
Answer & Solution
Correct Answer
(D) 32 P
Step-by-step Solution
Detailed explanation
\(P_1 V_1^\gamma = P_2 V_2^\gamma\) \(P_2 = P_1 \left(\frac{V_1}{V_2}\right)^\gamma\)
