Detailed explanation-1: -sublimation, in physics, conversion of a substance from the solid to the gaseous state without its becoming liquid. An example is the vaporization of frozen carbon dioxide (dry ice) at ordinary atmospheric pressure and temperature. The phenomenon is the result of vapour pressure and temperature relationships.

Detailed explanation-2: -One common example of sublimation is solid carbon dioxide, known as dry ice. At room temperature (293 K) and pressure (1.01 Bar), dry ice sublimates into carbon dioxide vapor. Sublimation is an endothermic process that happens below a substance’s triple point in its phase diagram.

Detailed explanation-3: -Sublimation is the process in which solid directly changes to gas.

Detailed explanation-4: -What is the sublimation process? Ans: Sublimation, including melting, freezing, and evaporation, is a form of phase transition, or shift in a state of matter. A substance transforms from a solid to a gas by sublimation without ever going through a liquid phase. A common example of sublimation is the dry ice, heavy CO2.

Detailed explanation-5: -Sublimation: The process in which a solid transforms into a gas phase without first melting to form a liquid phase. (Sublimation is not synonymous with evaporation; evaporation is a liquid-to-gas phase change.) Frequently happens with substances having a high vapor pressure at room temperature.
