Exothermic and Endothermic Reactions

Vocabulary flashcards reviewing exothermic and endothermic reactions, bond energies, thermal decomposition, and combustion.

Endothermic process

A process that takes in energy from its surroundings, where the energy needed to break bonds is greater than the energy released when making bonds.

Exothermic process

A process that releases energy to its surroundings making the surroundings hotter

Thermal decomposition

An endothermic reaction that involves breaking down bonds.

Combustion

An exothermic reaction where a substance reacts with oxygen and releases energy.

Bond breaking

A process that takes in energy.

Bond making

A process that releases energy as particles become more stable.
