Yes, this is why solid carbon dioxide is often called "dry ice." Instead of melting, it sublimes directly from a solid into a gas.

Does carbon dioxide gas change from a liquid to a solid at about -80 c?
No. the gas changes directly to a solid.
During the process of sublimation what happens?
A solid (like dry ice- solid carbon dioxide) turns directly to a gas, without being a liquid.
Dry ice converts directly to a foggy gas without melting physical or chemical change?
Dry ice is simple CO2 and at 1atm goes from a solid to a gas. Dry ice is solid Carbon dioxide and it changes physical state to gaseous Carbon dioxide without going through a liquid phase, this process of turning directly from a solid to a gas is called sublimation. As the chemical composition of the Carbon dioxide remains unchanged the change is entirely physical.
When a substance changes from a solid to a 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.
How do you change carbon dioxide from a solid to a gas?
You would heat it.
Does carbon dioxide gas change from a liquid to a solid at about -80 c?
No. the gas changes directly to a solid.
When a solid change directly into a gas it what?
Sublimation. Example: Dry ice turning into carbon dioxide
What must be done to carbon dioxide gas to change it to solid?
the cold air can change the carbon dioxide gas to a solid

What changes carbon dioxide gas back into carbon in a solid form?
the cold air can change the carbon dioxide gas to a solid
Does substances cannot change directly from a solid to a gas?
Yes, they can. This process is called sublimation. A good example of this can be found with dry ice, which is solid carbon dioxide. At pressures normally found on earth carbon dioxide cannot exist as a liquid, and instead will transition directly between the solid and gas states.
What are some substances that can change directly from gas to solid states?
Iodine does not go through a liquid when changing phase. Carbon dioxide does not go through liquid phase. Both iodine and carbon dioxide sublime from a solid to a gas and condense from the gas to a solid.

What is it called when a solid to gas?
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.
When a chunk of dry ice is at room temperature a cloud of carbon dioxide vapor forms. The carbon dioxide is changing from a?
The solid carbon dioxide is transformed directly in gaseous carbon dioxide; this phenomenon is called sublimation.
