What is the term for the act of breaking up and scattering or spreading a substance widely?

The act of breaking up and scattering or spreading a substance widely is known as dispersion. This process involves the distribution of particles or substances over a larger area or throughout a medium, such as water or air. In environmental contexts, dispersion can refer to the way pollutants or chemicals are spread out in aquatic systems, making it an important concept in aquatic pest management.

Dissipation generally refers to the gradual loss or waste of energy or resources, which does not capture the idea of spreading out a substance. Concentration involves bringing substances together in a smaller area, while aggregation pertains to the clustering or grouping of particles. Thus, dispersion is the appropriate term to describe the action of breaking up and widely distributing a substance.
