Changes of state, such as solid to liquid, or liquid to gas, are physical changes because no chemical reaction occurs. CO2 as a solid, a liquid, or a gas is still CO2. Generally, physical changes are easily reversed, so that if carbon dioxide is condensed from a gas to a liquid, it is easy to evaporate it back into a gas.
Frozen carbon dioxide is still carbon dioxide, so it is a physical change.
It is a change in physical state, which is 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-
true
Yes. It's a physical change because the chemical composition of the strawberries has not changed.

chemical change
We inhale oxygen and exhale carbon dioxide as a result of a change in our bodies. Answer - Chemical Change
No, it's a physical change.
It is a chemical change.
it's an example of physical change
no. a phase change is ALWAYS a physical change in the substance.
This is a chemical change.
Compounds do not get a new name when they change physical state. Carbon dioxide's name in the liquid state in just "liquid carbon dioxide"
No, it's chemical
