WebSublimation is an endothermic phase transition that occurs at temperatures and pressures below the triple point of a chemical in the phase diagram. The reverse process of sublimation is the process of deposition in which some chemicals pass directly from the gas phase to the solid phase, again without passing though the intermediate liquid phase.
