Which statement reflects Boyle's Law?

• A. V ∝ P at constant temperature
• B. V ∝ 1/P at constant temperature
• C. V ∝ P^2
• D. V is independent of P

Answer: (B)

Boyle's Law describes an inverse relationship between pressure and volume for a fixed amount of gas at constant temperature. The product PV stays constant, so as pressure increases, volume decreases proportionally to 1/P. This means volume is inversely proportional to pressure, which is why the statement V ∝ 1/P at constant temperature is the correct way to express the law. If you double the pressure, the volume should halve (ideally), keeping PV constant. The other forms—volume increasing with pressure, volume scaling with P^2, or volume being independent of pressure—do not match the inverse, isothermal behavior described by Boyle's Law.
