Dry ice can change from solid to gas without liquid state.
When this occurs it is called 'to sublime'
Ironisation is the process of changing gas into plasma. Other processes of changing state include: Solid -> liquid = melting Liquid -> gas = condensation Gas -> liquid = evaporation Liquid -> solid = freezing Solid <- -> Gas = sublimation
The process of a gas changing directly to a solid is called deposition. This occurs when the gas loses enough energy (usually through cooling) to transition directly from a gaseous state to a solid state. An example of this is when water vapor in the air turns into frost on a cold surface.
Sublimation
Examples of a gas changing directly into a solid (deposition) - Water vapor in a cloud changing into solid snowflakes. Water vapor in the air turning directly to frost on any sub-freezing surfaces.
sublimation
Gas to liquid. Also, gas to solid.
Changing directly from a gas to a solid is called deposition.Changing directly from a solid to a gas is called sublimation.

Gas changing into a solid is called deposition, where gas molecules lose energy and come together to form a solid. On the other hand, solid changing into a gas is called sublimation, where solid molecules gain enough energy to break free and become a gas without passing through the liquid state.
Water can be a solid, liquid, and gas at the same time. This is due to the varying energies of the molecules while they are in a changing state.
We know that there are four states of matter. Solid, liquid, gaseous and ionic (plasma) As one substance changes from one state into the other it is known as change of state Example: Ice (solid) melts into water (liquid) and gets evaporated ( gaseous) as water vapour.
A change of phase, from solid to liquid, or liquid to gas, or gas to liquid, etc., is also sometimes called a change of state.
Dry ice is the solid form (state of matter) of carbon dioxide (CO2).Under normal circumstances, it will change state from a solid directly to a gas. It does this without melting (changing state to a liquid). We call the direct transformation of a solid to a gas sublimation, and dry ice is said to sublime when going directly from its solid state to a gas.
according to kinectic particle theory the changing of state from solid to gas and gas to solid directly is sublimation eg sodium chloride.

A solid changing to a gas without becoming a liquid first is called sublimation.
