Temperature remaining constant, the pressure of gas is decreased by 20%. The percentage change in volume is (a) increases by 29% (b) decreases by 20% (c) increases by 25% (d) decreases by 25%

Answer: (c). Boyle's law: V ∝ 1/P at constant T. P' = 0.8P ⇒ V' = V/0.8 = 1.25V So the answer is (c): volume increases by 25%.
