Explosives are substances that produce violent chemical or nuclear reactions. These reactions generate large amounts of heat and gas in a fraction of a second. Shock waves produced by rapidly expanded gases are responsible for much of the destruction...

Warfare took a deadly step forward with the invention and development of powerful explosives in the nineteenth century. Guncotton and a safer explosive, cordite, supplied a "smokeless" propellant that made the battlefield visible. Big...

any substance or device that can be made to produce a volume of rapidly expanding gas in an extremely brief period. There are three fundamental types: mechanical, nuclear, and chemical. A mechanical explosive is one that depends on a physical reaction,...

Explosions occur when gases in a confined space expand with a pressure and velocity that cause stresses greater than the confining structure can withstand. The gas expansion can be caused by rapid generation of gaseous molecules from a solid or...

Any substance or device that can produce a volume of rapidly expanding gas in an extremely brief period. Mechanical explosives, which depend on a physical reaction (e.g., overloading a container with compressed air until it bursts), are little used...

Plosive with oral, medial release, e.g. the initial [th] (as opposed to the final unreleased in tat . ( also articulatory phonetics, aspiration)...

Compounds that are unstable and break down with the sudden release of large amounts of...

An explosive material is a material that either is chemically or otherwise energetically unstable or produces a sudden expansion of the material usually accompanied by the production of heat and large changes in pressure (and typically also a flash...
