''''Sublimation''' is the chemical process in which a pure [[chemical element]] or a [[chemical compound]] is converted from a solid state to a gaseous state without first passing through a liquid phase. The example most likely to be observed by non-[[chemist]]s is the conversion of [[dry ice]] into [[carbon dioxide]] gas. In chemistry labs, sublimation, when possible, serves as a very convenient method of chemical purification. The [[halogen]]s [[bromine]] and [[iodine]] are often purified in laboratories by sublimation. | |||
