yes
No, you can take the melted chocolate goo and pour it into a mold, cool it and re-form the candy bar. No, melting a chocolate bar is not an irreversible change. Melting a chocolate bar is just changing its state of matter. If you but the melted chocolate bar in a freezer, where exothermic processes will occur, and the chocolate bar will be solid again.
Melting a candy bar is a physical change because it is just changing form, not changing the chemical makeup. (If it isn't making a new material, it is not a chemical change)
Melting is endothermic. Freezing is exothermic.
No, freezing is exothermic as the water loses energy to its surroundings as it freezes.

candy bar
Speed Racer's favorite candy bar is a Japenese Candy Bar.
It is an endothermic process.
A candy bar becomes a tasty drink when it is transformed into a liquid form, typically through a process such as melting or blending. This can be achieved by heating the candy bar until it melts into a liquid consistency, or by blending it with a liquid such as milk or water to create a smooth, drinkable mixture. The resulting beverage will retain the flavors of the original candy bar, providing a unique and indulgent drinking experience.
No. It is a candy but not a bar.
freezing is exothermic, melting is endothermic, evaporation is endothermic, condensation is exothermic.
The answer is candy bar because it does not have to be baked
