Label this diagram of an endothermic reaction by dragging the correct words to the orange dots.
If you have to put in more energy than you get out, then the reaction is endothermic.
The term was coined by Marcellin Berthelot from the Greek roots endo-, derived from the word

Endothermic reactions can be used for everyday purposes. For example, certain sports injury cold packs
use endothermic reactions.
Breaking bonds (overcoming the force of attraction) requires . You have to put heat in - it is endothermic. This is why melting and boiling are .
Combustion is an endothermic reaction.
Endothermic means that during the reaction have moved from a lower state of energy to a higher state.
