Question

why diffision does not take place in solid ?
​

Answer 1

Answer:

Because the particles in a solid do not move.

Explanation:

Diffusion is the movement of particles from an area of high concentration to an area of low concentration, as the atoms in a solid are stationary (they vibrate in a regular arrangement due to being the state with the least energy), the particles cannot move and therefore cannot diffuse.

Answer 2

Answer:

If someone is cooking in the kitchen, the smell travels around the house to other rooms. This is because of diffusion, the movement of particles from an area of high concentration to an area of low concentration. For diffusion to work, the particles must be able to move around. This means that diffusion does not happen in solids the particles in a solid can only vibrate and cannot move from place to place.
