Endothermic processes.

Image An endothermic process is any process that involves, usually in the form of heat, or absorbs, energy from its environment. This may be a chemical process, such as ammonium nitrate dissolving in water, or a physical process, such as ice cube melting. All chemical reactions require both the breaking of existing chemical bonds and the formation of new ones. A reaction to breaking a bond often involves energy input and so this cycle is always endothermic. As atoms come together to form new chemical bonds, the combined electrostatic forces leave the bond with a substantial amount of energy. If t... Read More
