Boyle's law states that gases will contract under what conditions?

Boyle's law describes the relationship between the pressure and volume of a gas at constant temperature. According to this law, when the pressure on a gas increases, the volume decreases, assuming the temperature remains constant. Therefore, gases will contract or reduce in volume when pressure is applied. This principle is fundamental in understanding how gases behave under different physical conditions, particularly in applications such as breathing mechanisms and various engineering scenarios.

The other scenarios presented involve changes in temperature or volume that either do not directly correlate with pressure or suggest an increase in volume, which is contrary to the predictions of Boyle's law when considering a constant temperature environment.
