Question

Explain the reason for solids generally lacking the property of diffusion.

Answer 1

• Diffusion is a property of matter, which is based on the motion of its particles.
• It is defined as the net movement of particles from a region of high concentration to a region of low concentration.
• It occurs in solids, liquids, and gases.
• The rate of diffusion in solid is very very slow because the particles in solids are tightly packed and are held together by strong interparticle forces of attraction.
• They do not move from their fixed positions. the particles of solids vibrate only about their mean positions.
• The diffusion property is very slow in solids, due to the lack of movements in the particles of solids.

Therefore, solids generally lack the property of diffusion.
