Concept explainers
(a)
Interpretation: The partial pressure of oxygen on the plane should be calculated when the air is
Concept Introduction: According to the Dalton’s law of partial pressure, the sum of partial pressure of all gaseous components of the mixture is equal to the total pressure of a gaseous mixture. The partial pressure is product of mole fraction of gas and total pressure.
(b)
Interpretation: The total pressure of the cabin should be calculated at which the oxygen masks are dropped.
