Type: MCQ-numerical-Medium-Class 11

A cylinder contains 10 kg of gas at a pressure of 10710^7 N m2^{-2}. The quantity of gas taken out of the cylinder, if final pressure is 2.5×1062.5 \times 10^6 N m2^{-2} is

A

9.5 kg

B

7.5 kg

C

14.2 kg

D

zero

Correct Answer

Option B

Detailed Explanation

Using the relation P1P2=m1m2\frac{P_1}{P_2} = \frac{m_1}{m_2}, we find that the mass of gas remaining is 2.5 kg. Therefore, the mass of gas taken out is 10 kg - 2.5 kg = 7.5 kg.
