WebThe system (reaction) releases heat to the surroundings as the reactants transform into products. For example, the burning of wood releases heat. An exothermic reaction causes the surroundings to heat up. That explains why we feel hot when we stand beside a fire. The exothermic reaction is the opposite of the endothermic reaction [1-3].
