The change of a gas directly to a solid without going through the liquid state is called deposition.

It's the opposite of sublimation, where a solid directly changes into a gas.

Here are some examples of deposition:

* Frost formation: Water vapor in the air directly changes into ice crystals on cold surfaces.

* Snow formation: Water vapor in clouds directly changes into solid snowflakes.

* Dry ice sublimation: Solid carbon dioxide directly changes into gaseous carbon dioxide.

Deposition is a fascinating phenomenon that showcases the diverse states of matter and their interrelationships.
