Question

Give a suitable explanation for the following facts about gases.

Gases don’t settle at the bottom of a container

Short/Brief Note

Solution

Gases by definition are the least dense state of matter. They have negligible intermolecular forces of attraction. So they are all free to roam separately. So the least dense gas particles will not sink at the bottom of a container.
