Pick the noble gas used in deep-sea diving?
Neon
Argon
Helium
Krypton
Helium is used in deep-sea diving because it is less dense than air and nitrogen, which reduces the risk of decompression sickness. It also has a lower thermal conductivity, which reduces the amount of heat loss during extended periods of diving. Hence option C is the correct answer.
Option (A) is incorrect helium is used in deep-sea diving because it is less dense than air and nitrogen, which reduces the risk of decompression sickness. Hence option A is incorrect.
Option (B) is incorrect because helium is used in deep-sea diving because it is less dense than air and nitrogen, which reduces the risk of decompression sickness. Hence option B is incorrect.
Option (D) is incorrect because helium is used in deep-sea diving because it is less dense than air and nitrogen, which reduces the risk of decompression sickness. Hence option D is incorrect.
