AA loss of pressure
BEqual concentrations
CAll gas at one end
DComplete separation
Answer & Solution
Correct answer: B. Equal concentrations
1. Random molecular motion has no preferred direction.
2. Gases therefore spread until no gradient remains.
3. In a closed environment, diffusion will ultimately result in equal concentrations of gas throughout.
4. Separation would require something to drive the gases apart.
