Is melting chocolate reversable?
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.
Is melting a candy bar a chemical change?
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)
Is endothermic melting or freezing?
Melting is endothermic. Freezing is exothermic.
Which state changes are exothermic and endothermic?
freezing is exothermic, melting is endothermic, evaporation is endothermic, condensation is exothermic.
Is melting ice cubes endo or exothermic?
No, freezing is exothermic as the water loses energy to its surroundings as it freezes.
Is melting process a endothermic and exothermic?
endothermic
Is melting copper a exothermic process?
Endothermic Process.
Is melting an exothermic or an endothermic process?
It is an endothermic process.
Is freezing an example of an exothermic chemical change?
No because in an exothermic change energy is released not taken in. Melting would be an example of exothermic change.

candy bar
What conditions must be met for a reaction to be exothermic?
candy
What do you need to melt a solid in energy flow terms?
Melting is an exothermic process; we need heat for melting.
