Boyle's Law Explains Constant Temperature

Steps:

• Plot pressure (P) vs. volume (V) from data to check for inverse proportionality.
• Calculate PV product for each point; consistent values indicate ideal gas behavior at constant T.
• Compare to expected Boyle's law curve (V ∝ 1/P) for confirmation.
• Rule out deviations suggesting leaks or temperature changes.

Why B is correct:

• Boyle's law (PV = constant) holds only if temperature is constant, matching the inverse PV relationship in the data.

Why the others are wrong:

• A: Leaking would cause PV product to decrease after doubling pressure, not remain constant.
• C: Increasing temperature would raise PV product, causing volume to decrease less than inversely with pressure.
• D: Not enough information (option incomplete).

Final answer: B
