A deep sea diver breathes a mixture of 21% O2 and 79% He, which is at the local water pressure. The divers body contains 5 litres of blood; for simplicity, assume that blood behaves like water. Henry's law constant of helium is H He (T) = H He (To)exp AH He 1 To })] with HH (298K)=149700bar and AHH He T = 230K = a) Assume the blood (i.e., water at 36C) saturates with helium, and determine the amount (in moles) of helium dissolved in the blood at sea level and at a depth of 200 m. b) For both cases determine also the volume that the helium assumes at standard conditions. c) Explain in thermodynamic terms why the driver needs to decompress slowly.
