A type of reaction or process accompanied by the release of heat.
No. For example ammonium nitrate spontaneously dissolves in water. This is an endothermic process.
A chemical reaction that gives off heat ... like burning a candle.
Exos= outside , thermos=temperature or heat So within the definition itself it can be known that in exothermic reactions heat is released. In chemical reactions the energy supplied is use in breaking of bonds, but energy is release by making bonds. In exothermic reactions, the energy supplied is sufficient for chemical reaction to occur (to break existing bonds) and the excess energy is given in the form of heat (from making new bonds).If the reaction is exothermic, it means that the total energy it took to break the bonds is less than the total energy released when forming new bonds -- so net energy is released in the form of heat. for example 2H2 +O2 ----> 2H20 which is exothermic reaction. Combustion reactions in general are exothermic reactions.
Nothing to explain; that is the way EXO- and ENDOthemic reactions are called by definition
The combustion is exothermic.
A type of reaction or process accompanied by the release of heat.
A small amount of energy gets the reaction started, the formation of new compounds releases excess energy. That is the definition of exothermic.
No. For example ammonium nitrate spontaneously dissolves in water. This is an endothermic process.

a system consists of two kinds:the endothermic and exothermic reaction.
birds are winged, bipedal , exothermic, vertebrate animals that fly and lay eggs.
