## How does Boyle’s law relate to diving?

Boyle’s Law: For a fixed mass of gas at constant temperature, pressure and volume are inversely related. … As a diver descends, increase in pressure results in a decrease in gas volume (compression). Conversely, as the diver ascends compressed gas expands.

## How does the Charles Law relate to diving?

Charles’ Law does not relate to scuba diving. Charles’ Law is often used to explain why the pressure in a scuba tank goes up when the temperature increases. But Charles’ Law states that the volume of a gas is directly proportional to its temperature. The volume of a scuba tank is constant.

## How is the relationship of pressure and volume of gas related to the diver as he goes deeper into the water?

Pressure increases with ocean depth, and the pressure changes most rapidly as divers reach the surface. … If a diver is ascending, the air in his BCD expands because of lower pressure according to Boyle’s law (decreasing the pressure of gases increases the volume).

## How does decompression sickness relate to gas laws?

Decompression sickness, or “the bends,” is related more to Henry’s Law, which states that more gas will be dissolved in a liquid when the gas is pressurized. … However, if a diver ascends too quickly, nitrogen gas bubbles will form in body tissue rather than being exhaled.

## Why is Boyles Law important for divers?

Boyle’s Law is also important to divers because it means that if a diver takes a lung- ful of air while he is underwater, that air will expand in his lungs as he rises to the surface. If he holds his breath, or ascends too rapidly (like a cork) the expanding air can rupture his lungs.

## Which gas law best explains diving medical problems?

Henry’s law states that at a constant temperature, the amount of a gas that is dissolved in a liquid is directly proportional to the partial pressure of that gas. This law provides the explanation for decompression sickness and nitrogen narcosis.

## What would happen to a diver who does not exhale while surfacing from a 30 m dive?

What would happen to a diver who does not exhale while surfacing from a 30m dive? If divers must make emergency ascents from this depth they must remember to breathe out regularly as they return to the surface. If they don’t, the pressure of the air in their lungs will cause their lungs to expand.

## What is the relationship between gas pressure and volume?

More collisions mean more force, so the pressure will increase. When the volume decreases, the pressure increases. This shows that the pressure of a gas is inversely proportional to its volume. This is shown by the following equation – which is often called Boyle’s law.

## What is P1 V1 P2 V2?

According to Boyle’s Law, an inverse relationship exists between pressure and volume. … The relationship for Boyle’s Law can be expressed as follows: P1V1 = P2V2, where P1 and V1 are the initial pressure and volume values, and P2 and V2 are the values of the pressure and volume of the gas after change.
