It's called sublimation. Its undergoing a phase change. -APEX:)

It sublimes.

==================================
Another contributor continued:
The process is considered to be unusual among various substances, but the truth is that
it's rare only under the conditions in which human beings live, i.e., normal air pressure.
There is a threshold of pressure for every substance above which the substance has no
liquid phase, and passes directly between the solid and gaseous phases.
Example:
Above a pressure of about 214 atmospheres (3,120 pounds per square inch), water doesn't
exist. At that pressure, ice thaws directly to steam at 373° C (703° F), just as dry ice does
at room temperature and pressure..

What happens when sublimation takes place?
Sublimation is the change of state of matter from solid directly to gas. Dry ice does this. Deposition is the change of state from gas to solid. This is how frost forms. There are likely more examples of each, but they both skip over the liquid state of matter.
When a substance changes state what happens to its thermal energy?
Changes the temperature of the substance
Does gas come before solid or after solid?
Both! The physical state of a substance can go straight from gas to solid, or can heat from solid to liquid and then to gas. The process a solid undertakes when it goes straight to its gas state from a solid state without first turning liquid is called sublimation.
Is dry ice a solid liquid or a gas?
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.
What is the process when a solid turns to gas?
it is called deposition
What is the process involved in solid to gas?
A substance which changes state directly from a solid to a gas is said to have sublimed.
A sentence with sublimation?
In the process of sublimation, a substance goes from the solid state directly to the gas state.
What happens to the molecules of a substance as it moves from a liquid to a solid state?
use your book
What Happens at the start of a point?
At the start of a point the substance exists in a solid state
What happens when a substance changes from one state of matter to another?
It undergoes a phase change, such as when a solid (like frozen CO2) sublimates directly to a gas, or when water freezes to ice.
Sublimation?
This describes a unique property in which a substance can go from a solid to a gas without entering the liquid stage.
What type of change is it when a solid turns into a gas?
Sublimation - the process by which a substance goes directly from the solid to the gaseous state without passing through the liquid state.
What is the term for the process of a solid such as dry ice going directly from a solid to a gas?
The transition of a substance directly from the solid state to gas (such as dry ice to gas) is called "sublimation".
What happens when a substance changes state from a solid or liquid?
This change in the state of matter (liquid to solid) is called freezing.This change in the state of matter (solid to liquid) is called melting.They are physical change, the chemical nature of the molecules is not changed.
When a substance goes directly from a solid state to a gas state as dry ice does .?
It's called sublimation. Its undergoing a phase change. -APEX:)
Which substance changes from gaseous state to solid?
Those substances which undergo the process of sublimation change directly from solid to gas or from gas to solid. Example:- Ammonium chloride, Camphor
What substance conducts electricity in aqueous state but not in solid state?
ionic substance
