Scuba Project

Describing each of the gas laws:

Boyle's law- When the volume of a gas changes inversely with the pressure of a gas

Charles's law- Gases expand when temperature is added/heated.

Dalton's law- Says that in a mixture of non-reacting gases, all the pressure released is equal to the sum of the pressures of the individual gases.

Gay-Lussac's law- Temperature and pressure increase and decrease together but are not the same.

Henry's law- When staying at the same temperature, the amount of a given gas that dissolves in a type and volume of liquid, is directly proportional to the pressure of that gas.


Scuba Diving with Gas Laws

The different Conditions

The bends- You get it by being around nitrogen gas that is being released from the bloodstream and is caused by the bubbles that form in your blood when you dive deep into the ocean. It's very dangerous because it causes intense pain and can cause injuries involving the nervous system. You can treat the condition by suing a hyperbaric recompression chamber. The gas law that is involved include Boyle's law and henry's law.

Air embolisms- Happens when a scuba diver surfaces too quickly. It causes air to escape INTO the blood vessels from the lungs. The side affects of this condition include difficulty breathing, or respiratory failure. This can be treated by going into surgery and or you may have to start taking medications such as adrenaline to keep your heart pumping. The gas laws that are involved are boyle's law and henry's law.

Oxygen toxicity- It's a medical condition caused by the exposure to oxygen at high pressures. The dangers are that you could get nitrogen narcosis. There is no ways to treat this condition and the law that this portrays is Daltons law.
