Coffee dissolving, water boiling and chocolate melting are reversible physical transformations whereas wood burning is a chemical combustive transformation.
no! because burning is never a reversible change as heating is a reversible change e.g chocolate melting
neither
irreversable
No, for coal burning to be a reversible change, you would need the ability to take CO2 and turn it back into solid carbon.
Non reversible, after the wick has been burned, it is impossible to reverse the effects of the change.

Dissolving and fizzing are physical processes.
