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-
It is a chemical change. because starch present in bread is converted into carbon and carbon dioxide and reverse of the process is not possible.

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
