Question

Gases do not settle at the bottom of a container. This fact is explained by:

• A. Dalton's law
• B. Boyle's law
• C. Graham's law
• D. Kinetic theory of gases

Answer 1

The correct option is D Kinetic theory of gases

The $\text{kinetic theory of gases}$ explains the behaviour of gases. This theory describes a gas as a large number of small particles (atoms or molecules), all of which are in constant, random motion.

The rapidly moving particles constantly collide with each other and with the walls of the container.

So, the gases do not settle at the bottom of the container.

Hence, the correct answer is option $\text{D}$.
