According to Boyle's law, how is gas volume related to pressure?

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 the pressure on a gas increases, the volume decreases, and vice versa. The relationship can be mathematically expressed as PV = k, where P represents pressure, V represents volume, and k is a constant.

This relationship is fundamental in understanding how gases behave under different conditions and is essential in fields such as chemistry, physics, and various applied sciences. The correct answer reflects the core principle of Boyle's law, highlighting that changes in pressure will lead to changes in volume in opposite directions.

In contrast, options that suggest proportional relationships with pressure or temperature neglect the critical aspect of the inverse relationship defined by Boyle's law, which is why they do not align with the law's principle.
