Explosive - Wikipedia
An explosive (or explosive material) is a reactive substance that contains a great amount of potential energy that can produce an explosion if released suddenly, usually accompanied by the production of light, heat, sound, and pressure.

The Chemistry of Explosions - Department of Chemistry
Explosives are substances that undergo a rapid oxidation reaction with the production of large quantities of gases. It is the sudden buildup of gas pressure (see products above) that constitutes the nature of an explosion.

Aug 12, 2024 · Explosive Reactions. TNT is one of the most commonly used explosives for military, industrial, and mining applications. TNT has been used in conjunction with hydraulic fracturing, a process used to recover oil and gas from shale formations. The technique involves displacing and detonating nitroglycerin in hydraulically induced fractures ...
Explosives and explosions are all about chemistry. Although an explosion can be defi ned as a sudden increase in volume and release of energy in an extreme man-ner, explosions in the context of chemi-cal explosive are uncontrolled, uncon-tained, chemical reactions.
Explosions - Chemistry Encyclopedia - reaction, examples, gas, …
Chemical explosions may be either decomposition or combination reactions. In either case, the reaction is exothermic and the energy released by the reaction is partially converted to work. Decomposition reactions occur in materials such as trinitrotoluene (TNT) and nitroglycerine. The molecules of these materials contain oxygen.
Combustion - Explosions, Chemical Reactions, Heat | Britannica
Dec 21, 2024 · Combustion - Explosions, Chemical Reactions, Heat: The transition from combustion to explosion is caused by an acceleration of the reaction, induced either by a rise in temperature or by increasing lengths of the reaction chain.
types of explosives; both release large volumes of gas, and significant amounts of heat during the combustion. Basic principles of chemistry can be used to calculate such energy and volume changes that accompany the reaction of an explosive.
explosive substance is one which reacts chemically to produce heat and gas with rapid expansion of matter. A detonation is a very special type of ex plosion. It is a rapid chemical reaction, initiated by the heat accompanying a shock compression, which liberates sufficient energy, before any expan sion occurs, to sustain the shock wave.

What initiates such a controlled oxidation reduction reaction? Some energy stimulus such as a mechanical shock, a flame, or an electric spark touches it off. But what factors convert a sometimes simple reaction into an explosion?
