chemical b/c anything you burn is a chemical change :)
rawr.....
Physical never changes what it is; For example if you boil water its physical because you can change it back to water from precipitation, or if you tear a sheet of paper up it's still paper. Chemical- changes it's whole from it can never go back to what it was; Example, burning wood
burning in presence or absence of oxygen is a chemical change.
A fire (burning, combustion) is a chemical process.
it is both physical and chemical change
chemical changs in a bathroom ?
they are neither physical nor chemical changes
Physical. changes of state (solid, liquid, gas) are physical changes.
Burning is a chemical reaction with oxygen (oxidation).

Yes, burning (oxidation) is chemical change.

1. Melting of the candle is a physical change. 2. Burning and thermal decomposition are chemical changes.
Burning wood is a chemical change - although, like most chemical changes it is accompanied by a physical change. Usually we reserve the term physical changes for things like erosion, melting, or evaporation where no change in composition occurs.
Chemical change, because it is irreversible. The chemical composition of the substance actually changes. A physical change is a change of state, like water to ice. There, H20 is still H20.
