The act of exploding; detonation; a chemical action which causes the sudden formation of a great volume of expanded gas; as, the explosion of gunpowder, of fire damp, etc.
A bursting with violence and loud noise, because of internal pressure; as, the explosion of a gun, a bomb, a steam boiler, etc.
A violent outburst of feeling, manifested by excited language, action, etc.; as, an explosion of wrath.
a sudden and substantial increase; a rapid acceleration; as, the population explosion.
There is no fixed definition of an explosion. Events that are described as explosions include a rupturing water boiler, a flash of light created by an electrical short circuit, detonation of a high explosive, deflagration of a tank containing an explosive fuel-air mixture, or the shock wave, fireball, and debris cloud produced by a thermonuclear detonation. The AIChE suggests that an explosion is "A release of energy that causes a blast". Berthelot, the French chemist that pioneered the scientific study of explosions, is reputed (Bailey and Murray, Explosives, Propellants and Pyrotechnics, Brassey) to have defined an explosion in 1883 as "the sudden explosion of gases into a volume of much greater than their initial one, accompanied by noise and violent mechanical effects." A humourous definition was given by Joseph Needham, "An explosion may be defined as a loud noise accompanied by the sudden going away of things from the places where they were before." - see p. 110 of The Gunpowder Epic, Vol 5, Part 7, Science and Civilization in China.
Räjähdys Explosion 1.Flue gas side explosion is caused when a larger amount of unignited gases are accidentally accumalated in furnace and then burst into flames. 2. Smelt water explosion is caused when water comes contact with smelt located at furnace bottom. The explosion can cause vast material and personell injuries.The explosion can normally be prevented with the correct procedure of emergency shut down and rapid drainage and by using leak detectors.
(Explosion) Sudden and violent tearing asunder caused by gas or compressed air. This peril is usually insured under policies covering fire.
Like earthquakes, explosions are considered an Additional Peril that can be insured. Although a fire policy insures a property against fire that results from explosions, the concussion damage that can result is not covered apart from the limited coverage extended to gas used for domestic purposes. This should be covered under an explosion extension.
The sudden release of energy of sufficient magnitude to create a pressure wave. The energy to produce an explosion may come from a variety of sources; including nuclear, pressure or chemical reaction. 1. Examples of pressure related explosions include a rapid change in state (liquid to gas, for example) or by the over pressurization of a container (i.e., the failure of a gas cylinder). 2. A chemical explosion is the event in which a quantity of matter is instantaneously converted to gaseous product, with the generation of high temperature and pressure.
a type of eruption, taking place when the cap of dried lava blows off the volcano, releasing pressure and creating an explosion.
A rapid disintegration of an object. See clutch explosion.
The sudden conversion of chemical energy into kinetic energy with the release of heat, light and mechanical shock.
a violent release of energy caused by a chemical or nuclear reaction
a sudden great increase; "the population explosion"; "the information explosion"
the terminal forced release of pressure built up during the occlusive phase of a stop consonant
a sudden outburst; "an explosion of laughter"; "an explosion of rage"
a change in the state of matter that results in rapid and violent release of energy
a large-scale, noisy, rapid expansion of matter into a volume much greater than its original volume
an uncontrolled energy release resulting in a catastrophe
a perfect metaphor for sudden rage
a rapid expansion, outbreak, bursting, or upheaval
a release of energy in a sudden, loud and often violent manner with the generation of high temperature and usually with the release of gases
a sudden increase in volume and release of energy in aviolent manner, usually with the generation of high temperature and therelease of gases
a sudden increase in volume Volume (also called capacity) is a quantification of how much space an object occupies
a vague term used to describe an event associated with rapid energy release (see the glossary)
a very rapid and violent burning of a fuel
a violent expansion caused by instantaneous combustion of confined gases
a violent expansion of gas at high pressure
a violent process which begins, expands and finally exhausts itself and ends
An explosion for which the energy is produced by a nuclear transformation,either fission or fusion. The term typically implies the release of enormous amounts (kilotons) of energy.
A very rapid combustion of a substance using its own oxygen supply. Initiated by ignition.
A chemical reaction of any chemical compound or mechanical mixture that, when initiated, undergoes a very rapid combustion or decomposition releasing large volumes of highly heated gases that exert pressure on the surrounding medium. Also, a mechanical reaction in which failure of the container causes the sudden release of pressure from within a pressure vessel, for example, pressure rupture of a steam boiler. Depending on the rate of energy release, an explosion can be categorized as a deflagration, a detonation, or pressure rupture. Reference: DoD 6055.9 STD
A violent expansion, with force and noise, generally due to rapid chemical change; term covered under various property/casualty insurance policies.
The sudden conversion of potential energy (chemical or mechanical) into kinetic energy with the production and release of gases under pressure, or the release of gas under pressure. These high pressure gases then do mechanical work such as moving, changing, or shattering nearby materials.
1)A bursting of forces, usually from pressure from within. 2)In general, a rupture of a pressure vessel of some kind due to too much internal pressure, accompanied by a loud noise. Courts, however, have interpreted it in many ways.
A rapid expansion of material, often generating a blast wave and concussion. The collapses of the Twin Towers were characterized by the bursting out of thick clouds of material at rates of 50 feet per second, the hurling of projectiles 400 feet in all directions, and a blast wave that shattered windows in buildings 350 feet away. Thus their collapses are accurately described as explosions rather than as implosions, which are typically engineered by controlled demolitions.
A standard fire policy covers damage by fire, whether resulting from explosion or otherwise, and explosion of domestic-type and heating or lighting boilers only. It excludes other damage by explosion, whether the explosion is caused by a fire or not. Other explosion damage may be covered as an additional peril. Boiler explosion is also the subject of engineering insurance.
A rupture of a pressure vessel of some kind due to excessive internal pressure (usually accompanied by a loud noise).
A violent bursting or expansion as the result of the release of energy that causes great pressure discontinuity, or blast wave. It may be caused by an explosive or by the sudden release of pressure, as in the disruption of a steam boiler. An explosive produces an explosion by virtue of its very rapid self-propagating transformation into more stable substances, accompanied by the liberation of heat and the formation of gas. Depending on the rate of energy release, an explosion can be categorized as a deflagration, a detonation, or pressure rupture. See Blast Wave, Deflagration, Detonation, Detonation Wave, Shock Wave.
An extended coverage peril and currently a covered peril in nearly every policy of property insurance. The peril remains distinct from steam boiler explosion, which is covered by boiler & machinery insurance.
An explosion is a sudden increase in volume and release of energy in a violent manner, usually with the generation of high temperatures and the release of gases. An explosion causes pressure waves in the local medium in which it occurs. Explosions are categorized as deflagrations if these waves are subsonic and detonations if they are supersonic (shock waves).
