Exothermic reactions are like a campfire on a cold night. π₯ They release heat into their surroundings, making things warmer. Think of it as an explosion β it produces a lot of heat! These reactions decrease the energy of the system. The opposite is an endothermic reaction that needs heat. Burning wood, mixing acid and water, and many explosions are exothermic. Theyβre important in many processes from power generation to chemical synthesis.
