===Homogeneous mixtures===

====Solutions====
{{Main articles|Solution (chemistry)}}
A [[Solution (chemistry)|solution]] is equivalent to a "homogeneous mixture". In solutions, solutes will not settle out after any period of time and they cannot be removed by physical methods, such as a filter or [[centrifuge]].<ref name=solution>{{Cite encyclopedia | title =Solution (chemistry)| encyclopedia =Encyclopedia of Studies, New Edition| publisher = Online publisher: Science Online. Facts on File, Inc. | year =2001| last1 =Ashworth | first1 =William | last2 =Little | first2 =Charles E. <!--| access-date =2010–01-01-->}}</ref> As a homogeneous mixture, a solution has one phase (solid, liquid, or gas), although the phase of the solute and solvent may initially have been different (e.g., salt water).

====Gases====
Gases exhibit by far the greatest space (and, consequently, the weakest intermolecular forces) between their atoms or molecules; since intermolecular interactions are minuscule in comparison to those in liquids and solids, dilute gases very easily form solutions with one another. Air is one such example: it can be more specifically described as a gaseous solution of oxygen and other gases dissolved in nitrogen (its major component).
