Solution:
The above statement is true.Diffusion is the mixing of one substance with another substance to form a uniform mixture due to the movement of its particles. This property of matter is based on the movement of the particles. It is fastest in gases and slowest in solids. The particles must be able to move around for diffusion to work. Diffusion does not occur in solids because the particles in a solid can only vibrate and cannot migrate from one location to another. Because the particles in a solid are tightly packed around each other, it causes immobility of the particles in solids.
