Which of the following correctly describes Boyle's Law?

• A. The volume of a gas is directly related to its pressure
• B. The volume of a gas and its pressure are inversely related
• C. The pressure of a gas increases with an increase in volume
• D. The pressure of a gas is independent of its volume

Answer: (B)

Boyle's Law states that the volume of a gas is inversely related to its pressure when temperature and the amount of gas are held constant. This means that as the pressure exerted on a gas increases, the volume of that gas decreases, and vice versa. Mathematically, this relationship can be expressed as PV = k, where P is pressure, V is volume, and k is a constant. This inverse relationship occurs because gases tend to occupy more volume at lower pressures, allowing their molecules to spread out, while increased pressure forces the gas molecules closer together, resulting in a decrease in volume. Thus, the correct description of Boyle's Law is that the volume of a gas and its pressure are inversely related.
