Diffusion is a physical process where molecules of a material move from an area of high concentration (where there are many molecules) to an area of low concentration (where there are fewer molecules)until it has reached equilibrium (molecules evenly spread)

Answer 2

Explanation:

Diffusion is a physical process where molecules of a material move from an area of high concentration to lower.

OR

Diffusion is the net passive movement of particles (atoms, ions or molecules) from a region in which they are in higher concentration to regions of lower concentration.
