Web7 Apr 2024 · Sublimation is an analogous process to boiling, as it occurs when a compound's vapor pressure equals its applied pressure (often the atmospheric … WebSublimation is the process of direct transformation from the solid state to the gaseous state, without passing through a liquid phase. It is an endothermic phase transition that occurs at temperatures and pressures below the triple point of a substance, temperature and pressure in which the three phases coexist (Sublimation (chemistry), 2008).

Sublimation is the transition of a substance directly from the solid to the gas state, without passing through the liquid state. 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 …
WebExamples of Sublimation. One of the best examples of sublimation is dry ice, the frozen form of carbon dioxide. There is a direct change of phase of dry ice, from solid-state to gaseous state, when dry ice is exposed to air. It is visible as fog. The gaseous state of frozen carbon dioxide is more stable than its solid-state. WebSublimation is the opposite of vapor deposition. A vapor deposition technique is a coating process in which materials in a vapor state are condensed through condensation, chemical reaction, or conversion, to deposit thin films on different substrates and is classified as physical (PVD) and chemical (CVD) vapor deposition methods.
