2. Homogeneity and heterogeneity - Wikipedia

   en.wikipedia.org/wiki/Homogeneity_and_heterogeneity

   Homogeneity and heterogeneity; only ' b ' is homogeneous Homogeneity and heterogeneity are concepts relating to the uniformity of a substance, process or image.A homogeneous feature is uniform in composition or character (i.e. color, shape, size, weight, height, distribution, texture, language, income, disease, temperature, radioactivity, architectural design, etc.); one that is heterogeneous ...

3. Mixture - Wikipedia

   en.wikipedia.org/wiki/Mixture

   These terms are derived from the idea that a homogeneous mixture has a uniform appearance, or only one phase, because the particles are evenly distributed. However, a heterogeneous mixture has constituent substances that are in different phases and easily distinguishable from one another. In addition, a heterogeneous mixture may have a uniform ...

4. Mixture (probability) - Wikipedia

   en.wikipedia.org/wiki/Mixture_(probability)

   In probability theory and statistics, a mixture is a probabilistic combination of two or more probability distributions. [1] The concept arises mostly in two contexts: A mixture defining a new probability distribution from some existing ones, as in a mixture distribution or a compound distribution. Here a major problem often is to derive the ...

5. Dispersion (chemistry) - Wikipedia

   en.wikipedia.org/wiki/Dispersion_(chemistry)

   A colloid is a heterogeneous mixture where the dispersed particles have at least in one direction a dimension roughly between 1 nm and 1 μm or that in a system discontinuities are found at distances of that order. [8] A suspension is a heterogeneous dispersion of larger particles in a medium. Unlike solutions and colloids, if left undisturbed ...

6. Suspension (chemistry) - Wikipedia

   en.wikipedia.org/wiki/Suspension_(chemistry)

   In chemistry, a suspension is a heterogeneous mixture of a fluid that contains solid particles sufficiently large for sedimentation. The particles may be visible to the naked eye, usually must be larger than one micrometer, and will eventually settle, although the mixture is only classified as a suspension when and while the particles have not ...

7. Powder mixture - Wikipedia

   en.wikipedia.org/wiki/Powder_mixture

   A random mixture can be obtained if two different free-flowing powders of approximately the same particle size, density and shape are mixed (see figure A). [3] Only primary particles are present in this type of mixture, i.e., the particles are not cohesive and do not cling to one another. The mixing time will determine the quality of the random ...
