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

It sublimes.

∙ 13y agoWhen a substance changes directly from solid state to gaseous state without changing to the liquid state, it undergoes sublimation. Examples of substances which sublime include dry ice and ammonium chloride.
==================================
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.
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 is the change over from gas directly to solid called?
The change from gas directly to solid is called deposition. It occurs when a substance transitions from the gaseous state to the solid state without passing through the liquid state.
Sublimation?
This describes a unique property in which a substance can go from a solid to a gas without entering the liquid stage.
When something goes from a solid directly to a gas what is it called?
The process of a substance changing from a solid directly to a gas is called sublimation. This occurs when the substance's vapor pressure exceeds its atmospheric pressure at a certain temperature, allowing it to transition from a solid state to a gaseous state without passing through the liquid phase.
What is it called when a solid turns into a gas for kids?
When a solid turns into a gas, it is called sublimation. This is when a substance changes directly from a solid state to a gas state without passing through the liquid state in between.
A sentence with sublimation?
Ice sublimated directly into water vapor without melting into liquid water.
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:)
What type of change is it when a solid turns into a gas?
It is a phase change called sublimation, where a solid transitions directly into a gas without passing through the liquid phase.
What is solid to gas called for a phase change?
The phase change from solid to gas is called sublimation. It occurs when a substance transitions directly from a solid state to a gas state without passing through the liquid state.
Which substance changes from gaseous state to solid?
Carbon dioxide changes from a gaseous state to a solid state through the process of deposition. This occurs when carbon dioxide gas directly turns into solid carbon dioxide ice without transitioning into a liquid state first.
