Final answer:
Solids lack diffusion due to their fixed particle positions and strong intermolecular forces, preventing them from freely moving. This rigidity hinders their ability to exhibit diffusion compared to fluids and gases.
Explanation:
Solids generally lack the property of diffusion because the individual particles of a substance in a solid state are in fixed positions due to strong intermolecular forces, preventing the particles from moving freely to diffuse.
In solids, there is not enough thermal energy to overcome the intermolecular interactions between particles, resulting in a definite shape and volume. This rigidity hinders the ability of solids to exhibit diffusion compared to fluids and gases.
Due to the tightly packed structure and fixed positions of particles in solids, the process of diffusion, which involves the movement of particles from an area of high concentration to low concentration, is impeded in solids.
