What is described by Boyle's law regarding reverse squeeze?

• A. Gases compress in deeper water
• B. Gases expand upon ascent
• C. Gases dissolve more in warm water
• D. Gases are completely inert

Answer: (B)

Boyle's law states that at a constant temperature, the volume of a given mass of gas is inversely proportional to the pressure exerted on it. In the context of diving and reverse squeeze, when a diver ascends, the external pressure decreases. This reduction in pressure allows gases that are dissolved in the body (such as nitrogen absorbed during a dive) to expand. If a diver ascends too quickly, the gases can expand rapidly, potentially leading to the formation of bubbles, which is referred to as reverse squeeze. This phenomenon is particularly important for divers to understand, as managing ascent rates is crucial for preventing decompression sickness. The understanding of how gases behave under changing pressure conditions, as described by Boyle's law, is therefore essential in dive medicine.
