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: -Examples of Solid to Gas (Sublimation) Dry Ice-Solid carbon dioxide is known as “dry ice” and sublimates at room temperature. Freeze-drying-Water can be sublimated in a food product by using a vacuum.
Detailed explanation-3: -The process uses the science of sublimation, in which heat and pressure are applied to a solid, turning it into a gas through an endothermic reaction without passing through the liquid phase.
Detailed explanation-4: -The best example of sublimation is dry ice which is a frozen form of carbon dioxide. When dry ice gets exposed to air, dry ice directly changes its phase from solid-state to gaseous state which is visible as fog.
