We inhale oxygen and exhale carbon dioxide as a result of a change in our bodies. Answer - Chemical Change
The physical change that is happening is called sublimation. Sublimation is when a solid (snow) directly turns into a gas (carbon dioxide) without passing through the liquid state.
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.
This is a chemical change.
Frozen carbon dioxide is still carbon dioxide, so it is a physical change.
When coal is burnt the chemical change combines carbon from the coal with oxygen from the air to produce carbon dioxide.
When coal is burned, the carbon in the coal combines with oxygen in the air to form carbon dioxide. This carbon dioxide is released into the atmosphere as a greenhouse gas, contributing to climate change.

It is a chemical change.
Yes, carbon from the log combines with the air to form co2.

no. a phase change is ALWAYS a physical change in the substance.
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-
