Gunpowder is a chemical mixture historically used as a propellant in firearms, artillery, and fireworks. Its composition typically includes sulfur, charcoal, and potassium nitrate (saltpeter).
When ignited, gunpowder undergoes a rapid exothermic oxidation-reduction reaction, producing hot gases that generate pressure.
This pressure propels projectiles or causes explosive effects. Gunpowder played a pivotal role in military history, revolutionizing warfare, and continues to be employed in various applications, including pyrotechnics. Its invention is attributed to Chinese alchemists and dates back to ancient times.
