⫸ Sublimation is the process when, a substance transforms from a solid to a gas without ever going through a liquid phase.

⫸ It includes melting, freezing, and evaporation, is a form of phase transition, or shift in a state of matter.

⫸ It occurs when the particles of a solid absorb enough energy to completely overcome the force of attraction between them. Solid carbon dioxide changes directly to the gaseous state.

⫸ Example :- Snow and ice can sublime in the winter months without melting.

Mothballs and camphor are also an examples of sublimate solids.

⫸ Sublime substance :- camphor, dry ice, iodine crystals, arsenic.
