According to Boyle's Law, what happens to a balloon’s volume when pressure decreases?

• A. The volume stays the same
• B. The volume expands
• C. The volume contracts
• D. The volume disappears

Answer: (B)

Boyle's Law states that the volume of a given mass of gas is inversely proportional to its pressure, provided the temperature remains constant. This means that as pressure decreases, the volume of the gas must increase to maintain the relationship defined by the law. In the context of a balloon, when the external pressure applied to the balloon is reduced, the gas molecules inside the balloon are less compressed and are thus able to spread out more. This causes the balloon to expand in volume. Therefore, the correct answer reflects that as pressure decreases, the volume of the balloon indeed expands, allowing it to occupy more space.
