Explanation:
The statements which are true are as follows.
- A solid can diffuse into both a liquid and another solid.
- A liquid can diffuse into another liquid.
- A gas can diffuse into another gas.
When we heat a solid it starts to melt as a result it diffuses into liquid. Whereas when we write with a chalk on a blackboard then the solid particles of chalk disperse on the solid surface of blackboard.
Therefore, a solid can diffuse into solid as well but the rate of diffusion is slow.
When we mix two liquids they tend to mix with each other. As a result, they diffuse into each other.
Similarly, a gas can diffuse into another gas as there is weak force of attraction between gas molecules and high kinetic energy. As a result, rate of diffusion is fast in gases.
