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.
Best Answer: An exothermic reaction gives off heat, as oppose to an endothermic reaction, which takes in heat. If you put in heat to make the reaction happen, then it is endothermic. If the reaction makes the surroundings hotter, then it is exothermic. E.g. melting ice requires heat, so it is endothermic.
