Will diffused gases separate from a mixture because of their weight difference?

In the context of gas mixtures, it's important to understand that diffused gases do not separate solely based on their weight differences. While it is true that heavier gases can settle below lighter gases due to gravity, the process of diffusion and the nature of gas behavior in mixtures typically prevents stratification.

Gases are constantly in motion, and the kinetic energy associated with this motion means that lighter gases can intermingle with heavier gases, leading to an even distribution throughout the mixture rather than a clear separation. This behavior is a result of the principles of thermodynamics and gas laws that govern how gases interact with one another. In a closed system or at typical atmospheric conditions, diffusion will tend to create a uniform mixture rather than allowing for stratification based on weight.

The other choices imply conditions or variables that don't align with the general behavior of gases in a mixture, further reinforcing why they do not capture the concept accurately.
