Vedclass · Answer

(A) Deep sea divers face the risk of 'the bends' (decompression sickness) due to the high solubility of nitrogen in blood under high pressure. When the diver ascends,the pressure decreases,causing nitrogen to form bubbles in the blood,which can be fatal. Helium is used as a diluent for oxygen because it is much less soluble in blood than nitrogen,even at high pressures,thereby preventing the formation of bubbles during decompression.

Helium is added to the oxygen supply used by deep sea divers because

Why are gases highly compressible?

At $T \ K$,equal weights of $H_2, D_2$,and $T_2$ are present in a closed vessel. The pressure exerted by this gaseous mixture is $P \ atm$. The ratio of partial pressures of $T_2, D_2$,and $H_2$ is approximately. ($H, D$ and $T$ are isotopes of hydrogen).
