The explosion process, often referred to as detonation or deflagration depending on its speed, is a rapid release of energy causing a sudden increase in volume and pressure. This phenomenon typically occurs when a substance, known as an explosive, undergoes an extremely fast chemical reaction. The reaction front propagates through the explosive material, breaking chemical bonds and forming new, more stable molecules. This process releases a significant amount of thermal energy and generates a large volume of hot gases.

The rapid expansion of these gases is what creates the characteristic shockwave and pressure pulse associated with an explosion. The speed at which this reaction front travels dictates the type of explosion. Detonation involves a supersonic reaction front that is driven by the shockwave it creates, leading to extremely high pressures and temperatures. Deflagration, on the other hand, is a subsonic combustion process, typically slower and less violent than detonation, though still capable of causing significant damage due to rapid gas expansion.

The composition of the explosive material is crucial. Explosives are often mixtures containing both a fuel and an oxidizer, or a single molecule with both components integrated. The specific chemical structure and the presence of an ignition source, such as heat, friction, or impact, initiate the chain reaction. Understanding the explosion process is vital in fields like mining, demolition, pyrotechnics, and in the study of accidental industrial incidents and military applications.
