Gas Laws & Ideal Gas Equation

At constant temperature, the volume of a gas is to be decreased by 4%. The pressure must be increased by

Show answer and solution

Answer: (b)

Boyle's law at constant $T$ : $PV = \text{constant}$ , so $P' = \dfrac{PV}{V'}$ .
$V' = 0.96V \Rightarrow P' = \dfrac{P}{0.96} = 1.0417P$
Increase $\approx 4.17\%$ , i.e. about $4.16\%$ .
So the answer is (b) $4.16\%$ .
