Challenge Question: What is the minimum size of the chamber? Note: we know its 4ft high. *0.20=89.8mol O 2.
Given that the average human needs about 11,000 liters of air per day, and air is approximately 20% oxygen determine the minimum amount of moles of oxygen that must have been present in the bubble.
At 30 meters (depth of the boat sinking) the pressure is 4 atm, assume the water was 60 F (15.5 C). Determine the volume that the amount of air you calculated above would take.
Given that height is 4ft or 1.2 meters and assuming a square area:
So what is the verdict when all these are factored in? A space of about 25-177 meters required.
