What aspect of the kinetic theory of gases tells us that the gases will mix?

The answer to the question: What aspect of the kinetic theory of gases tells us that the gases will mix? Would be: The Kinetic Molecular theory of gases.

Explanation:

Although the theory is much bigger than just to explain what happens to gases when they are together in a space, it does help to understand a few things. First, that gases, at their most elemental particle, which is their molecules and atoms, because of their state, have freedom of motion and kinetic energy and therefore are always moving and colliding with one another. The second thing that it explains is that two gases, because their molecular and kinetic properties are the same for both, will mix together always if they are close to one another and their particles will mix and collide. It is these collisions between gas particles that explain the pressure of a gas and its magnitude.
