What does Boyle's Law state about gas volume and pressure?

Boyle's Law states that for a given mass of an ideal gas at constant temperature, the volume of the gas is inversely proportional to its pressure. This relationship can be observed in the formula PV = k, where P represents pressure, V represents volume, and k is a constant. As pressure increases, the volume decreases, and vice versa, provided that the temperature remains unchanged.

This law reflects the fact that if the volume of a gas is reduced, the molecules have less space to move around, which results in more frequent collisions against the walls of the container, leading to an increase in pressure. Conversely, if the volume increases, the pressure exerted by the gas decreases because the molecules have more space to move and collide less frequently with the walls. Hence, the correct response accurately captures the inverse relationship described by Boyle's Law.
