This page provides all possible meanings and translations of the word Sublimation
(chemistry) a change directly from the solid to the gaseous state without becoming liquid
(psychology) modifying the natural expression of an impulse or instinct (especially a sexual one) to one that is socially acceptable
The transition of a substance from the solid phase directly to the vapor state such that it does not pass through the intermediate liquid phase.
The transformation of an impulse into something socially constructive.
Origin: From sublimationem.
the act or process of subliming, or the state or result of being sublimed
the act of heightening or improving; exaltation; elevation; purification
that which is sublimed; the product of a purifying process
Origin: [LL. sublimatio: cf. F. sublimation.]
Sublimation is the transition of a substance directly from the solid to the gas phase without passing through an intermediate liquid phase. Sublimation is an endothermic phase transition that occurs at temperatures and pressures below a substance's triple point in its phase diagram. The reverse process of sublimation is desublimation, or deposition. At normal pressures, most chemical compounds and elements possess three different states at different temperatures. In these cases, the transition from the solid to the gaseous state requires an intermediate liquid state. Note, however, that the pressure referred to here is the partial pressure of the substance, not the total pressure of the entire system. So, all solids that possess an appreciable vapor pressure at a certain temperature usually can sublime in air. For some substances, such as carbon and arsenic, sublimation is much easier than evaporation from the melt, because the pressure of their triple point is very high, and it is difficult to obtain them as liquids. Sublimation requires additional energy and is an endothermic change. The enthalpy of sublimation can be calculated as the enthalpy of fusion plus the enthalpy of vaporization.
The Nuttall Encyclopedia
the vaporisation of a solid body and its resumption thereafter of the solid form.
U.S. National Library of Medicine
A defense mechanism through which unacceptable impulses and instinctive urges are diverted into personally and socially acceptable channels; e.g., aggression may be diverted through sports activities.
