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

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 of the gas decreases, provided the temperature and the amount of gas remain unchanged. This inverse relationship can be summarized as: when you compress a gas, reducing its volume, the pressure inside that confined space becomes greater due to the increased frequency of gas molecules colliding with the walls of the container.

In practical terms, if you were to squeeze a balloon, for instance, the volume of air inside would reduce as the pressure on the gas increases, illustrating Boyle's Law effectively. This principle is crucial in aeromedical contexts, as it helps explain how pressure changes in the environment can affect gases within the body, such as during ascents and descents in an aircraft.

The other options do not accurately reflect Boyle's Law; for instance, a direct variation would imply that both volume and pressure increase or decrease together, which contradicts the inverse nature of their relationship as established by Boyle's Law. Additionally, stating that the volume of gas is constant at varying temperatures misrepresents the nature of gas behavior, as volume can change with temperature, leading to the need for further laws, such
