The gas mixture which is used by the divers inside the sea is
Show Hint
Helium is used in deep-sea diving to prevent decompression sickness and nitrogen narcosis.
Updated On: Apr 16, 2026
- O\(_2\) + N\(_2\)
- O\(_2\) + Ar
- O\(_2\) + Xe
- O\(_2\) + He
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept:
Deep sea divers use specialized gas mixtures to avoid the toxic effects of nitrogen under high pressure.
Step 2: Detailed Explanation:
At high pressure, nitrogen dissolves in the blood and can cause "the bends" (decompression sickness). Helium is used to dilute oxygen because it is less soluble in blood than nitrogen and has a much lower density, making breathing easier at depth. The common mixture is heliox (O\(_2\) + He).
Step 3: Final Answer:
Divers use a mixture of oxygen and helium, which corresponds to option (D).
