==Description==

An [[explosion]] is a rapid increase in [[volume]] and release of [[energy]] in an extreme [[manner]], usually with the generation of high [[temperatures]] and the release of [[gases]]. An explosion [[creates]] a [http://en.wikipedia.org/wiki/Shock_wave shock wave]. If the shock wave is a supersonic detonation, then the [[source]] of the blast is called a "[http://en.wikipedia.org/wiki/High_explosive high explosive]". Subsonic shock waves are [[created]] by [http://en.wikipedia.org/wiki/Low_explosives low explosives] through the slower burning [[process]] known as [http://en.wikipedia.org/wiki/Deflagration deflagration].

The generation of [[heat]] in large [[quantities]] accompanies most explosive [[chemical]] [[reaction]]s. The exceptions are called [http://en.wikipedia.org/wiki/Entropic_explosion entropic explosives] and include [[organic]] peroxides such as [http://en.wikipedia.org/wiki/Acetone_peroxide acetone peroxide].  It is the rapid [[liberation]] of [[heat]] that causes the [[gaseous]] products of most explosive [[reactions]] to expand and generate high [[pressures]]. This rapid generation of high [[pressures]] of the released [[gas]] constitutes the explosion. It should be noted that the [[liberation]] of [[heat]] with insufficient rapidity will not cause an explosion. For example, although a pound of coal yields five times as much [[heat]] as a pound of [http://en.wikipedia.org/wiki/Nitroglycerin nitroglycerin], the coal cannot be used as an explosive because the rate at which it yields this [[heat]] is quite slow.[http://en.wikipedia.org/wiki/Explosion]
