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.

∙ 9y agoDry ice, which is solid carbon dioxide at room temperature is a physical change. From being solid, it becomes gas at room temperature.
Wiki User
∙ 12y agoDry ice is frozen carbon dioxide. If it evaporates, that is a physical change.
Wiki User
∙ 14y agoCarbon dioxide changing from solid dry ice to a gas is a change of physical state, the chemical composition and formula still remains the same.

∙ 11y agoThe sublimation of dry ice into gaseous carbon dioxide is a physical change. It does not undergo any chemical changes.
Wiki User
∙ 11y agoIt's a physical change because it's still carbon dioxide.

∙ 8y agoDry 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 freezing carbon dioxide a chemical change or physical change?
Frozen carbon dioxide is still carbon dioxide, so it is a physical change.
What is the sublimation of carbon dioxide a chemical property or chemical change?
It is a change in physical state, which is a physical change.
Is burning coal a chemical or physical reaction?
It is a chemical reaction. The coal (which is mostly carbon) reacts with oxygen to form carbon dioxide.
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.
Is combining carbon dioxide and water to make sugar a physical change?
Combining carbon dioxide and water is a chemical change, not a physical change, but it doesn't make sugar. Carbon dioxide and water makes carbonic acid. CO2 + H2O <--> H2CO3-->H+ + HCO3-
Dry ice turning into carbon dioxide physical or chemical?
i think it is chemical but it may be physical.
Is freezing carbon dioxide a chemical change or physical change?
Frozen carbon dioxide is still carbon dioxide, so it is a physical change.
What type of change is oxygen turning into carbon dioxide?
Chemical
What is the sublimation of carbon dioxide a chemical property or chemical change?
It is a change in physical state, which is a physical change.
Is carbon dioxide a physical or chemical property?
Carbon dioxide (CO2) is a chemical compound consisting of one carbon atom bonded to two oxygen atoms. It is a chemical property because it describes the composition and arrangement of atoms in a substance. However, in terms of physical properties, carbon dioxide is a colorless, odorless gas at standard temperature and pressure.
When carbon dioxide comes from the fuel of the car is it a physical or chemical change?
chemical change
When ethanol is burnt and converted into carbon dioxide and water is that a chemical or physical change?
chemical
What is the chemical equation for turning carbon dioxide into oxygen and carbon?
The equation is:2 CO2 ===========> 2 CO + O2
Is burning coal a chemical or physical reaction?

Is it physical or chemical change when acid on limestone produces carbon dioxide gas?
It is a chemical change.
Is antacid tablet fizzing and releasing carbon dioxide in the stomach physical or chemical?
This is a chemical process.
