Question

Quizplus · Accepted Answer

An exothermic process is one in which heat is evolved, meaning it is released into the surroundings. This is in contrast to an endothermic process, which absorbs heat from the surroundings, and an endergonic process, which requires an input of energy. Combustion is a specific type of exothermic reaction in which a fuel reacts with oxygen to produce heat and light.
