By heating chocolate is melted; after this chocolate is thermally decomposed. Chocolate gas doesn't exist.

Yes, because water can be removed by heating and vaporization.
Yes. It's just like ice to water and back to ice. - - - - - "Reaction" implies a chemical change. Melting chocolate is a physical change. (Hardening melted chocolate can involve a whole series of physical changes but that's a different issue.)
It’s reversible
chocolate is reversible when you melt it put it in the freezer but if you eat it it will not be reversible
yes,joule is a heating reversible effect .
No, there are other ways of reversible, such as moving
Monkies
yes
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.
Burning is not reversible because it involves a chemical reaction that permanently changes the substances involved. Heating, on the other hand, is reversible since it involves providing energy to increase the temperature but can be reversed by removing the heat.
Heating steel detempers it, it makes it softer.
Coffee dissolving, water boiling and chocolate melting are reversible physical transformations whereas wood burning is a chemical combustive transformation.
it can't be changed,i.e.,irreversible change...
