Which property of gases is explained by the process of diffusion according to the kinetic molecular theory?

• A. The ability of gas particles to spread and mix uniformly throughout a container
• B. The tendency of gases to occupy the lowest possible volume
• C. The increase in pressure with increasing temperature
• D. The formation of a liquid from a gas at low temperatures

Answer: (A)

Verified step by step guidance

1. Understand that diffusion is the process by which gas particles spread out and mix due to their random motion.
2. Recall that the kinetic molecular theory explains gas behavior based on the motion and collisions of particles.
3. Identify that diffusion occurs because gas particles move rapidly and randomly, causing them to spread evenly throughout a container.
4. Recognize that this spreading and mixing is a direct consequence of the kinetic energy and constant motion of gas particles described by the kinetic molecular theory.
5. Conclude that the property explained by diffusion is the ability of gas particles to spread and mix uniformly throughout a container.
