At 10 ×104 Pa pressure and 300 K temperature, the volume of 0.09 mol CO 2 gas is 22.4 × 10−3 m3. What will be the volume of the gas if the pressure is decreased to 2 × 104 Pa ?

A. 112.0 ×10−3 m3
B. 37.4 × 10−3 m3
C. 56.3 × 10−3 m3
D. 28.1 × 10−3 m3
Answer: Option A
Solution (By JKSSB Mock Tests Team)
According to Boyle's Law, formulated by Robert Boyle in 1662, the pressure and volume of a gas have an inverse relationship at a constant temperature. Using the formula P1V1 = P2V2, decreasing the pressure by a factor of five mathematically increases the volume to 112.0 × 10−3 m3.
