i think it is chemical but it may be physical.
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.
chemical change
The equation is:2 CO2 ===========> 2 CO + O2
CO2 is the chemical formula of carbon dioxide.
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.

Frozen carbon dioxide is still carbon dioxide, so it is a physical change.

This is a chemical change.
We inhale oxygen and exhale carbon dioxide as a result of a change in our bodies. Answer - Chemical Change
