According to ____, as altitude increases and pressure decreases, gas expansion causes the available oxygen to decrease as gas molecules move farther apart.

Question

Quizplus · Accepted Answer

Dalton's Law states that the total pressure of a gas mixture is the sum of the partial pressures of its individual gases. As altitude increases and pressure decreases, the partial pressure of oxygen decreases, leading to less oxygen available for breathing. This occurs because gas molecules move farther apart as pressure decreases, leading to expansion and the decrease in the concentration of oxygen molecules in the mixture.
