Detailed explanation-1: -Sublimation is the transition of a substance directly from the solid phase to the gas phase without passing through the intermediate liquid phase (Table 4.8, Fig. 4.2). Sublimation is an endothermic phase transition that occurs at temperatures and pressures below the triple point of a chemical in the phase diagram.
Detailed explanation-2: -We can define sublimation as the transition of a substance from the solid phase to the gaseous phase without changing into the liquid phase. This process is an endothermic phase transition that occurs at a temperature and pressure below the triple point of the substance.
Detailed explanation-3: -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).
Detailed explanation-4: -Answer: Solution: Sublimation is the process by which a substance changes from solid state directly to vapour state.
Detailed explanation-5: -SUBLIMATION: The change of the solid state of the matter directly on heating to vapor state (without becoming liquid) is called sublimation.
