neither
no! because burning is never a reversible change as heating is a reversible change e.g chocolate melting
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.
It's irreversible

yes,joule is a heating reversible effect .
reversible
Burning is an irreversible change.
No, there are other ways of reversible, such as moving
Burning or combustion is always a chemical change sugar on burning produce carbon dioxide and water vapours which can neither be again change in sugar, while a physical change is always reversible.
the latter
No, it is not.
