:Deposition (chemistry)

{{About||the phase transition from gas to solid|Deposition (phase transition)|other uses|Deposition (disambiguation)}}

In chemistry, deposition occurs when molecules settle out of a solution. Deposition can be defined as the process of direct transition of a substance from its gaseous form, on cooling, into a solid state without passing through the intermediate liquid state.{{Citation |last=ten Elshof |first=J.

Deposition can be viewed as a reverse process to dissolution or particle re-entrainment.{{Cite journal |last1=Yung |first1=B. P. K. |last2=Merry |first2=H. |last3=Bott |first3=T.
