The phase change in which a substance goes directly from solid to gas without passing through the liquid phase is called sublimation.

Some common examples of sublimation include:

* Dry ice (solid carbon dioxide) sublimating into carbon dioxide gas.

* Mothballs (solid naphthalene) slowly disappearing as they sublimate into gaseous naphthalene.

* Frozen water (ice) sublimating into water vapor in a cold, dry environment.
