In chemistry, a mixture is a material made up of two or more different chemical substances which can be separated by physical method. It is an impure substance made up of 2 or more elements or compounds mechanically mixed together in any proportion. [ 1 ]

In statistics, a mixture model is a probabilistic model for representing the presence of subpopulations within an overall population, without requiring that an observed data set should identify the sub-population to which an individual observation belongs.

在化学中，混合物（mixture）是由两种至多種不同的纯净物（单质或化合物）沒有經化學合成而混合成的体系，例如溶液、胶体、浊液等。 混合物无法用 化学式 表达。

In probability and statistics, a mixture distribution is the probability distribution of a random variable that is derived from a collection of other random variables as follows: first, a random variable is selected by chance from the collection according to given probabilities of selection, and then the value of the selected random variable is ...

In chemistry, a mixture is a substance that is made up of two or more simpler substances. These substances can be chemical elements or compounds . A mixture can be made of liquids , solids , or gases .

A mixture is a combination of two or more chemicals, in which the chemicals retain their identity. Mixture may also refer to: Mixture (probability), a set of probability distributions often used for statistical classification; Mixture (organ stop), a special kind of pipe organ stop which has several pipes to each note

An ideal solution or ideal mixture is a solution that exhibits thermodynamic properties analogous to those of a mixture of ideal gases. [1] [2] The enthalpy of mixing is zero [3] as is the volume change on mixing. [2]The vapor pressures of all components obey Raoult's law across the entire range of concentrations, [2] and the activity coefficient (which measures deviation from ideality) is ...
