Key Concepts

Endothermic Process

An endothermic process absorbs energy from its surroundings, typically resulting in a cooling effect. This energy uptake is often required to overcome the bonds in a material or to drive a phase transition, such as a solid changing directly to a gas, where the process consumes heat to proceed.

Exothermic Process

An exothermic process is one that releases energy, usually in the form of heat, into its surroundings. In many chemical reactions such as combustion, molecules react in a way that the energy released when new bonds form exceeds the energy required to break the original bonds, resulting in a net release of energy.
