# How does partial pressure affect the movement of oxygen?

The movement of ${O}_{2}$ gas particles is but nominally affected by normal partial pressures of itself and constituent gases in mixtures of it.

#### Explanation:

I think this is what you're asking, but maybe I'm wrong.

Partial pressure is the pressure of a constituent gas in its mixture. ${O}_{2}$ gas particles aren't significantly affected by the the partial pressures of other gases in a mixture, due to kinetic-molecular theory stating that gas particles take up a negligible volume.

However, if the mixture is pressurized enough ${O}_{2}$ may deviate from kinetic-molecular theory along with the other gases in the mixture.
