D)The volume of the particles is negligible compared to the volume of the gas.

Question

The assumption that a gas consists of tiny particles moving in random straight line motion is most frequently cited to explain diffusion of a gas. Diffusion is the random movement of particles from an area of high concentration to an area of low concentration, and this assumption is foundational to understanding how and why this occurs in gases.
