Yes, because water can be removed by heating and vaporization.
By heating chocolate is melted; after this chocolate is thermally decomposed. Chocolate gas doesn't exist.
It’s reversible
Because - you can simply evaporate the water by heating it, and collect the water in a separate vessel - leaving the dry sand intact.
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.)
no! because burning is never a reversible change as heating is a reversible change e.g chocolate melting
yes,joule is a heating reversible effect .
chocolate is reversible when you melt it put it in the freezer but if you eat it it will not be reversible
No, there are other ways of reversible, such as moving
Monkies
neither
yes
Heating steel detempers it, it makes it softer.
it can't be changed,i.e.,irreversible change...
Coffee dissolving, water boiling and chocolate melting are reversible physical transformations whereas wood burning is a chemical combustive transformation.
