What is heterogen?

eous mixtures:

Heterogeneous mixtures are composed of two or more substances that are not uniformly distributed or mixed evenly. In these mixtures, the components can be visually distinguished or separated by physical means such as filtration, sedimentation, or centrifugation. Examples of heterogeneous mixtures include soil, sand and water, oil and water, salad, and blood. The properties of the components in a heterogeneous mixture can vary, and their interaction is often limited. The composition and distribution of the components in heterogeneous mixtures is not consistent throughout the mixture. Thus, the characteristics of a heterogeneous mixture depend on the size, shape, and concentration of the substances present in the mixture.
