No, burning wax is an irreversible change. When wax is burned, it undergoes a chemical reaction that changes it into different substances (carbon dioxide, water vapor, and heat) that cannot be easily reversed.
No, burning a candle is not reversible. When a candle is burned, the wax is melted and the wick is consumed, resulting in irreversible changes to the candle's structure.
Coffee dissolving, water boiling and chocolate melting are reversible physical transformations whereas wood burning is a chemical combustive transformation.
Burning a candle is a non-reversible change because once the wax is melted and the wick is burnt, it cannot be undone to return the candle to its original state. The chemical composition of the wax and wick is changed permanently.
it can't be changed,i.e.,irreversible change...

yes,joule is a heating reversible effect .
Burning is an irreversible change.

No, there are other ways of reversible, such as moving
No, it is not.

Heating steel detempers it, it makes it softer.

Yes, candle burning is a reversible change because it can be undone by extinguishing the flame. When the flame is removed, the wax solidifies again, demonstrating that the process of burning is reversible by cooling down the wax.
