Answer: The statement diffusion occurs when particles spread from areas where they are less concentrated to areas where they are more concentrated, is false.
Explanation:
When particles or atoms of a substance are able to move rapidly from one place to another then it is called diffusion.
During diffusion, particles tend to move apart from each other.
For example, spreading of dye molecules into water.
Thus, we can conclude that the statement diffusion occurs when particles spread from areas where they are less concentrated to areas where they are more concentrated, is false.
Evaporation is one change.
