A) helium is much less soluble in blood than nitrogen
B) nitrogen is much less soluble in blood than helium
C) due to high pressure deep under the sea nitrogen and oxygen react to give poisonous nitric oxide
D) nitrogen is highly soluble in water
Correct Answer: A
Solution :
\[He\text{-}{{O}_{2}}\] (80% : 20%) mixture is used by deep sea divers for artificial respiration. Because of low intermolecular forces in He, it is much less soluble in aqueous solutions (as compared to\[{{N}_{2}}\]) such as blood and does not cause caiseion sickness or bends by bubbling out of blood when the worker moves from high pressure (while in deep sea) to atmospheric pressure.You need to login to perform this action.
