Today’s word - endothermic
An endothermic reaction is one that absorbs or uses heat energy. Just ask a melting snowman about it.What do green leaves, boiled eggs, and split gas molecules have in common? They have all undergone endothermic reactions, absorbing heat. But just because there’s heat involved doesn’t mean an endothermic reaction is the cause.
