WebSublimation. Figure 1: A piece of solid carbon dioxide (dry ice) sublimating from a solid directly into a gas. [1] Sublimation is a type of phase change that takes place when a solid turns directly into a gas, skipping the liquid phase. The opposite of sublimation is vapour deposition. The term "sublimation" only applies to a physical change of ... WebSublimation is an endothermic phase transition in which a solid evaporates to a gas. Solids that sublimate have such high vapor pressures that heating leads to a substantial vaporization even before the melting point is reached.
