# Why does a scuba diver need to have high gas pressure (~ 3000 psi in the air tank?

## Why does a scuba diver need to know about gas laws in order to enjoy diving without danger?

Air spaces in the body are subjected to pressure and volume change, in direct proportion to your depth. Without doubt, understanding Boyle’s Law is very important in scuba diving. … From 10msw to surface the pressure halves. If you breath hold, the air in your lungs will double in volume causing a ruptured lung.

## What happens to the pressure of the gases in the tank as you dive deeper Why?

Simply put-as a diver goes deeper into the water, the pressure on everything becomes greater. The volume of air in the dive tanks is getting smaller while the pressure rises. Remember from the basics that you can compress air. This also means that the air in the divers lungs also becomes compressed when at depth.

## How do gas laws relate to scuba diving?

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.

## Why is it important for scuba divers must pay attention to the solubility of gases in the blood?

Henry’s Law states that the solubility of a gas in a liquid is proportional to the partial pressure of the gas over the liquid. This is important to SCUBA divers, because more nitrogen dissolves in their blood when they breathe compressed air at depth.

## 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.

## Why is Charles law usually irrelevant to scuba 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.

## Why can’t humans go deep underwater?

Since the water down at those depths is still liquid and not solid, there is not enough depth in our ocean to solidify water simply with pressure. Water remains a liquid at even 1101 bar or pressure. The human body would therefore not solidify under that pressure.

## Why can’t divers go straight up?

Decompression sickness: Often called “the bends,” decompression sickness happens when a scuba diver ascends too quickly. Divers breathe compressed air that contains nitrogen. … And if a diver rises to the surface (decompresses) at the right rate, the nitrogen can slowly and safely leave the body through the lungs.

## Is scuba diving hard on your body?

Scuba diving exposes you to many effects, including immersion, cold, hyperbaric gases, elevated breathing pressure, exercise and stress, as well as a postdive risk of gas bubbles circulating in your blood. Your heart’s capacity to support an elevated blood output decreases with age and with disease.

## What are the 5 gas laws?

Gas Laws: Boyle’s Law, Charle’s Law, Gay-Lussac’s Law, Avogadro’s Law.

## How does Charles law apply to diving?

Charles’ Law states that at a constant volume, the pressure of gas varies directly with absolute temperature. … When the balloon is exposed to colder temperatures, the molecules of the gas slow down, causing the balloon to deflate. This concept is the same in regard to air in a SCUBA tank.

## Why does a scuba diver need increased gas?

Why does a scuba diver need increased gas pressure in the air tank? Because the deeper the diver descends the more pressure that is applied to the body, the increase allows for divers to breathe under these extreme pressures.

## What is Henry’s law and its application?

Answer: Henry’s law states that the solubility of a gas in a liquid is directly proportional to the pressure of the gas. … (iii) To avoid bends (painful effects during the decompression of scuba divers), oxygen diluted with less soluble helium gas is used by the sea divers.
