What happens to the volume of air trapped in a caged environment as pressure increases at depth?

As a diver descends, the pressure surrounding them increases. According to Boyle's Law, which states that the volume of a gas is inversely proportional to the pressure exerted on it (when temperature is constant), the volume of air trapped in a caged environment will decrease as pressure increases.

This means that if you have a certain amount of gas (air) at the surface and then take it to a deeper depth where the pressure is higher, the gas will occupy a smaller volume. This principle is important for divers to understand because it affects buoyancy, the expansion of air in lungs and other gas spaces in the body, and ensures that the diver manages air supply properly to avoid issues such as barotrauma.

The other responses do not accurately reflect the behavior of gases under increased pressure, thus reinforcing the understanding of Boyle's Law as it pertains to diving.
