<span>The process when molecules tend to move from an area of high concentration to an area of low concentration is diffusion! I hope I helped :D</span>
In the diffusion process, a substance moves from a high concentration zone to a low concentration zone until both concentrations are equal throughout the space. An example could be if a bottle of ammonia is opened in a room. The ammonia molecules will initially be more concentrated where the bottle was opened. Gradually, the ammonia molecules will spread far from where they were released, and you can smell the ammonia at the ends of the room.
