Exothermic and Endothermic Reactions | GCSE Chemistry
Energy is always conserved in chemical reactions, but it can be transferred between the system and surroundings.
Is a self-heating can an exothermic or endothermic process?
What is Exothermic and Endothermic Reactions | GCSE Chemistry?
"Terms used to describe whether a chemical reaction releases or absorbs energy."
In an exothermic reaction, what happens to the temperature of the surroundings?
Which of these is an application of an endothermic reaction?
Why is bond breaking considered an endothermic process?
Energy Change Facts
Exothermic: Gives out heat (surroundings get hotter).
Endothermic: Takes in heat (surroundings get colder).
Bond breaking is endothermic; bond making is exothermic.
Keyword: "Overall" energy change. If energy released > energy taken in, it is exothermic.
