Diffusion patterns refer to the way substances, such as gases or liquids, spread out in a given space. This process occurs due to the movement of particles from areas of higher concentration to areas of lower concentration, resulting in a more even distribution over time. Common examples include the way perfume scent travels through a room or how food coloring disperses in water. In nature, diffusion patterns can be observed in various contexts, such as the dispersal of seeds by wind or water. These patterns are influenced by factors like temperature, pressure, and the properties of the substances involved, affecting how quickly and evenly they spread.
