<P> Sublimation is the phase transition of a substance directly from the solid to the gas phase without passing through the intermediate liquid phase . Sublimation is an endothermic process that occurs at temperatures and pressures below a substance 's triple point in its phase diagram , which corresponds to the lowest pressure at which the substance can exist as a liquid . The reverse process of sublimation is deposition or desublimation , in which a substance passes directly from a gas to a solid phase . Sublimation has also been used as a generic term to describe a solid - to - gas transition ( sublimation ) followed by a gas - to - solid transition ( deposition ) . </P>
