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.

Is freezing carbon dioxide a chemical change or physical change?
Frozen carbon dioxide is still carbon dioxide, so it is a physical change.
When baking biscuits and other quick breads the baking powder reacts to release carbon dioxide bubbles the carbon dioxide bubble causes the dough to rise is this a physical or chemical change and why?
The reaction of baking powder to release carbon dioxide bubbles is a chemical change because it involves the formation of new substances (carbon dioxide gas) due to a chemical reaction. The carbon dioxide bubbles cause the dough to rise through physical expansion, but the underlying process of gas production is a chemical 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.
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-
What is the sublimation of carbon dioxide a chemical property or chemical change?
The sublimation of carbon dioxide is a physical change, not a chemical property or change. Sublimation is the process in which a substance transitions directly from a solid to a gas without going through the liquid phase, and it does not involve any change in the chemical composition of the substance.
Dry ice turning into carbon dioxide physical or chemical?
i think it is chemical but it may be physical.
What type of change is oxygen turning into carbon dioxide?
Chemical
Is freezing carbon dioxide a chemical change or physical change?
Frozen carbon dioxide is still carbon dioxide, so it 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 ethanol is burnt and converted into carbon dioxide and water is that a chemical or physical change?
chemical
When carbon dioxide comes from the fuel of the car is it a physical or chemical change?
chemical change
What is the chemical equation for turning carbon dioxide into oxygen and carbon?
The equation is:2 CO2 ===========> 2 CO + O2
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.
What is the name of this compound CO 2?
CO2 is the chemical formula of carbon dioxide.
Is a heating process onto carbon dioxide a chemical reaction or a physical reaction?
Heating carbon dioxide is a physical reaction because it does not change the chemical makeup of the substance, only its physical state. The heat energy causes the carbon dioxide molecules to vibrate more rapidly, increasing their kinetic energy and leading to a phase change from solid to gas.
When Acid is placed into limestone and produces carbon dioxide gas is this a physical or a chemical change?
This is a chemical change.
