An endothermic reaction or process takes place when the system absorbs heat energy from the surrounding environment. In an exothermic reaction or process, energy is released into the environment, usually in the form of heat, but also electricity, sound, or light.
An exothermic reaction releases heat into the surroundings, and an endothermic reaction absorbs heat from the surroundings. Frying an egg is an example of an endothermic process because the egg solidifies as it absorbs heat from the frying pan. A common example of an exothermic reaction is combustion in the form of a bonfire -- anyone near the flames can readily determine that the fire is releasing heat into the surroundings.
