Question

A solid diffuse in other solid at a :

• A. zero rate
• B. very slow rate
• C. fast rate
• D. very fast rate

Answer 1

The correct option is A

zero rate

An explanation for correct answers:

• The solid particles are very closely packed and keep on vibrating about their mean positions.
• Diffusion is the movement of particles from the higher concentration region to the lower concentration.
• There is no diffusion in solids as they are closely packed and have no spaces between them for them to move.

An explanation for incorrect answers:

There is no diffusion in solids so it does not diffuses at a slow rate, fast rate, or very fast rate.

Hence, the correct option is A.
