Sublimation is the process by which a solid changes into its gaseous state without changing to its liquid state and vice versa.

Sublimation occurs due to the presence of very weak bonds in between the molecules of a particular substance. Hence, it changes into its gaseous state on heating very mildly or at room temperature.

Example : Naphthalene, Ammonium chloride etc.
