![]() Ī heterogeneous mixture is a mixture of two or more compounds. Entropy allows for heterogeneous substances to become homogeneous over time. For example, adding dye to water will create a heterogeneous solution at first, but will become homogeneous over time. Heterogeneous solids, liquids, and gases may be made homogeneous by melting, stirring, or by allowing time to pass for diffusion to distribute the molecules evenly. In chemistry, a heterogeneous mixture consists of either or both of 1) multiple states of matter or 2) hydrophilic and hydrophobic substances in one mixture an example of the latter would be a mixture of water, octane, and silicone grease. Main article: Homogeneous and heterogeneous mixtures Various disciplines understand heterogeneity, or being heterogeneous, in different ways. This is known as an effective medium approximation. Hence, an element may be homogeneous on a larger scale, compared to being heterogeneous on a smaller scale. From atoms to galaxies, plants, animals, humans, and other living organisms all share both a common or unique set of complexities. The concepts are the same to every level of complexity. Similarly, heterogenous is a spelling traditionally reserved to biology and pathology, referring to the property of an object in the body having its origin outside the body. But use of homogenous to mean homogeneous has seen a rise since 2000 sufficient enough for it to now be considered an "established variant". Īlternate spellings omitting the last -e- (and the associated pronunciations) are common, but mistaken: homogenous is strictly a biological/pathological term which has largely been replaced by homologous. ![]() ![]() The words homogeneous and heterogeneous come from Medieval Latin homogeneus and heterogeneus, from Ancient Greek ὁμογενής ( homogenēs) and ἑτερογενής ( heterogenēs), from ὁμός ( homos, “same”) and ἕτερος ( heteros, “other, another, different”) respectively, followed by γένος ( genos, “kind”) -ous is an adjectival suffix. color, shape, size, weight, height, distribution, texture, language, income, disease, temperature, radioactivity, architectural design, etc.) one that is heterogeneous is distinctly nonuniform in at least one of these qualities. A homogeneous feature is uniform in composition or character (i.e. ![]() Homogeneity and heterogeneity are concepts relating to the uniformity of a substance, process or image.
