What does Boyle's Law explain?

Boyle’s Law specifically addresses the relationship between the pressure and volume of a gas when temperature is held constant. It states that at a constant temperature, the pressure of a gas is inversely proportional to its volume. This means that if the volume of the gas decreases, the pressure increases, and vice versa. This fundamental principle is crucial for divers, as it helps them understand how gas behaves under different pressures experienced underwater.

Understanding Boyle’s Law is vital for preventing conditions such as barotrauma, which can occur when pressure changes rapidly during ascent or descent. Divers must recognize how their equipment, as well as the air in their lungs, will respond to changing pressures in the underwater environment. The other options pertain to different gas laws or concepts not covered by Boyle’s Law, such as the relationships between temperature and pressure or the levels of gases, which are not the focus of Boyle’s observations.
