Answer 2

Answer:

Diffusion is a physical process that refers to the net movement of molecules from a region of high concentration to one of lower concentration.

The rate of this movement is a function of temperature, viscosity of the medium, and the size (mass) of the particles. Diffusion results in the gradual mixing of materials, and eventually, it forms a homogeneous mixture.
