Question

2. Explain why - (i) Solids do not undergo diffusion whereas liquids and gases undergo diffusion readily​

Answer 1

Answer:

In solids , the particles are tightly packed therefore the kinetic energy is low and hence solids do not undergo diffusion. whereas liquids and gases the particles are less tightly packed and hence diffusion occurs faster.

Answer 2

Answer:

Solids do not undergo diffusion because their particles are very tightly packed and the intermolecular forces are strong in solids. But in liquids and gases, the particles are not so much tightly packed and they are free to move. They diffuse more readily than solids due to their arrangements of particles.
