Question

Deep sea divers use a mixture of:

• A. Helium - Oxygen
• B. Nitrogen - Oxygen
• C. Hydrogen - Nitrogen
• D. Helium - Nitrogen

Hint:

Helium is less soluble in blood compared to nitrogen, reducing the risks for divers when breathing under high pressure.

Answer 1

The Correct Option is A

Deep sea divers use a mixture of: 

• Option 1: Helium - Oxygen - This is the correct answer. Deep sea divers often use a mixture of helium and oxygen, known as heliox, to avoid nitrogen narcosis and to reduce the risk of decompression sickness at great depths.
• Option 2: Nitrogen - Oxygen - This is commonly used in regular air for diving, but at greater depths, it can cause nitrogen narcosis. This is not the best option for deep sea divers.
• Option 3: Hydrogen - Nitrogen - This is not typically used in diving, as hydrogen is highly flammable and would pose significant risks to divers.
• Option 4: Helium - Nitrogen - This is not a typical gas mixture for deep sea diving. Helium is usually mixed with oxygen, not nitrogen, for deep diving.

Explanation:

Deep sea divers use a mixture of helium and oxygen (heliox) to prevent the risks associated with using air at extreme depths, such as nitrogen narcosis and oxygen toxicity. Helium is an inert gas and does not cause narcosis, making it safer for deep diving.
