Deposition, by definition in chemistry, refers to a phase transition in which matter transitions directly from a gaseous state into a solid state without passing through an intermediate liquid phase.
The opposite is Sublimation
"freezing" is liquid, not gas, to solid. Please bot use Google or something.
