Melting is a process involving absorption of energy, which means that it is endothermic. A process whereby energy is released into the atmosphere or surrounding region is called an exothermic process. More »

Endothermic, or heat-absorbing, processes include melting ice cubes, evaporating liquid water, melting solid salts, cooking an egg, baking bread, separating ion pairs and splitting a gas molecule. Other examples include ... More »

Endothermic is a process or reaction that absorbs energy in the form of heat. Endothermic reactions feel cold because it is taking heat away. Breaking a chemical bond is endothermic because it needs energy. More »

Sublimation is an endothermic process, which means that energy must be added to a substance to facilitate the process. Sublimation is the term that describes a solid substance turning directly into a gas. More »

The difference between exothermic and endothermic reactions is found in their names: "endo" means to draw into itself, whereas "exo" means to emit. All chemical reactions either release or use energy, which can be in the... More »

Freezing water is an exothermic process because there is a release of energy into the environment in the form of heat. In an exothermic reaction, the change in enthalpy or measure of heat content, is negative. More »
