Gas Laws & Ideal Gas Equation

The volume of given mass of a gas is decreased by $7\%$ at constant temperature. The pressure should be increased by

Show answer and solution

Answer: (c)

Boyle's law: $P \propto \dfrac{1}{V}$ at constant $T$ .
$V' = 0.93V \Rightarrow P' = \dfrac{P}{0.93} = 1.0753P$
Increase $\approx 7.5\%$ .
So the answer is (c) $7.52\%$ .
