The process is called sublimation. Solids can turn directly into gases, and gases can turn directly into solid without ever being a liquid. Carbon dioxide (dry ice) is a common example of this. Other examples are mothballs, solid air fresheners (Air Wick), and iodine.
The dramatic change from solid to gas in one step is called sublimination, the most common example of sublimination is dry ice, dry ice at near room temperature or colder sublime automatically as white wisps of gas. With most elements that are solid at room temperature, however, need a large amount of heat to get it subliming.
The process of changing phases directly from a solid to a gas is called sublimation. A common molecule that sublimesis Carbon dioxide (CO2).
Sublimation. This is also the other way around.
This change is called sublimation.

Sublimation
Melting: the substance changes back from the solid to the liquid. Condensation: the substance changes from a gas to a liquid. Vaporization: the substance changes from a liquid to a gas. Sublimation: the substance changes directly from a solid to a gas without going through the liquid phase.
A solid (like dry ice- solid carbon dioxide) turns directly to a gas, without being a liquid.
A physical change.Changes between Solid, Liquid, and Gas.
The change in state from a solid directly to a gas is called sublimation. An example is frozen carbon dioxide which changes directly into gaseous carbon dioxide without going through a liquid phase.
GAS
A phase change directly from a gas to a solid is called deposition.
A phase change directly from a gas to a solid is called deposition.

Sublimation.
solidification
Submilation is when you change something directly from a gas to a liquid, with out changing it into a liquid first.
sublimation Sometimes solids can change directly into a gas without becoming a liquid first. The most common substance that goes directly from solid to gas is Carbon Dioxide. It goes directly from solid (dry ice) to gas.
The melting point.
Those substances which undergo the process of sublimation change directly from solid to gas or from gas to solid. Example:- Ammonium chloride, Camphor
Because the entropy is negative making it spontaneous.
