It is a physical change because even though it is a gas, it can be made back into what it used to be. Just like ice melts into water and water heats and evaporates to gas. Water can easily be frozen back to ice. Gas can turn back to water.
Dry ice sublimating is a physical change of carbon dioxide between a solid state and a gaseous state without going through a liquid state. If it were s chemical change, than it would no longer be carbon dioxide after changing state.

∙ 12y agoYes, since it is changing from a solid directly to a vapor. It's still carbon dioxide either as a solid or gas.

Is dry ice subliming a physical change or a chemical change?
A physical change. It's chemically still CO2, whether solid or a gas.
Is dry ice a chemical change or a physical change?
I just had this question for a chemistry and it is a physical change
What is dry ice physical or chemical change when left unattended?
Physical change, called sublimation. It still stays CO2
Is dry ice turning into Carbon dioxide physical or chemical?
It is a physical change of state. CO2 solid (dry ice) is still CO2 as a gas.What does change is the physical heat content of the substance. By absorbing heat the physical state is changed from a solid at -109.3 degrees F to a gas at -109.3 degrees F. All the heat absorbed for the change of state is used by the molecules to expand in size (external energy), rather than to change in temperature. There is also a small amount of energy loss due to this change (entropy). Another calculation made is internal energy which is the internal molecular motive energy of the substance.
Why is dry ice disappearing a chemical change?
It isn't. Answer --> It is an example of phase change and thus a physical change. Not a chemical change
What is a physical change A fermenting grapes to produce wine B baking a cake C a tomato ripening D dry ice subliming E digesting a meal?
D. Dry ice subliming is a physical change. Chemically, it's still CO2.
Is dry ice subliming a physical change or a chemical change?
A physical change. It's chemically still CO2, whether solid or a gas.
Is subliming ice a chemical change?
No, sublimation is a change of state, so it is a physical process.
Is dry ice smoking at a concert is a physical or chemical change?
It is a physical change.
Is dry ice a chemical change or a physical change?
I just had this question for a chemistry and it is a physical change
Is dry ice changing into theatrical smoke physical or chemical change?
Dry ice doesn't "turn into smoke". Dry ice causes moisture in the air to condense, forming fog. This is a purely physical, not chemical, change.
Is mealting dry ice a chemical change or physical change?
Any type of melting is a physical change.
Is the temperature at which dry ice evaporates a chemical or physical?
Physical Change
Is it physical or chemical when dry ice evaporates without melting as time passes?
It is a physical change because the composition of the dry ice didn't change; it just changed forms
Why is dry ice evaporation a physical chainge?
Dry ice is a solid form of cooled carbon dioxide. When it reaches room temperature it changes to gaseous carbon dioxide. Since, there is no change in the chemical composition of dry ice, it is called a physical change.
Is a piece of dry ice changing into a gas a physical change?
Yes
Melting of polar lce caps physical change?
The melting of ice is a physical change. The physical change include physical change include sublimating dry ice, boiling water, crushing an aluminum can or breaking a glass bottle.
