A material in which the first three factors exist cannot be accepted as an explosive unless the reaction can be made to occur when needed. List of the largest artificial non-nuclear explosions. The Spin Cycle segment also returned for a time. Note that the contents of the container may cause a subsequent chemical explosion, the effects of which can be dramatically more serious, such as a propane tank in the midst of a fire. From Wikipedia, the free encyclopedia. Explosions can occur in nature. Reaction heat is measured under conditions either of constant pressure or constant volume.

Another type of large astronomical explosion occurs when a very large meteoroid or an asteroid impacts the surface of another object, such as a planet. The energy source for solar flare activity comes from the tangling of magnetic field lines resulting from the rotation of the Sun’s conductive plasma.
Explosion – Wikipedia
Explosions can also occur outside of Earth in the universe in events such as supernova. A chemical explosive is a compound or mixture which, upon the application of heat or shock, decomposes or rearranges with extreme rapidity, yielding much gas and heat.
An explosion is a rapid increase in volume and release of energy in an extreme manner, usually with the generation of high xplosikn and the release of gases. This page was last edited on 11 Novemberat Views Read Edit View history.

Retrieved aor ” https: Beginning in DecemberRockstar Spud replaced long term color commentator Mike Tenay, who thereafter stood in for Spud in from time to time when Spud could not make the tapings. Unless the reaction occurs very rapidly, the thermally expanding gases will be moderately dissipated in the medium, with no large differential in pressure and there will be no explosion. The speed of the reaction is what distinguishes an explosive reaction from an ordinary combustion reaction.
For other uses, see Explosion disambiguation. Explosion at Wikipedia’s sister projects.
For the song by OutKast, see Stankonia. Combustion Deflagration Detonation Dust explosion Explosion protection Explosive limit Fuel tank explosion Implosion mechanical process: The show was reformatted with families in mind, as it aired on Saturday mornings in the UK. Reaction heat is measured under conditions either of constant pressure or constant volume.
Sports entertainment Professional wrestling. It is this heat of reaction that may be properly expressed as the “heat of explosion. Occasionally, wrestlers may have made their debut or return on Xplosion and angles also took place. Boiling liquid expanding vapor explosions are one type of mechanical explosion that can occur when a vessel containing a pressurized liquid is ruptured, causing a rapid increase in volume as the liquid evaporates.

As the fire burns, there certainly is the evolution of heat and the formation of gases, but neither is liberated rapidly enough to build up a sudden substantial pressure differential and then cause an explosion. Retrieved from ” https: A high current electrical fault can create an ‘electrical explosion’ by forming a high energy electrical arc which rapidly vaporizes metal and insulation material.
A positive value indicates that heat is absorbed during the formation of the compound from its elements; such a reaction is called an endothermic reaction. Examples include an overheated boiler or a simple tin can of beans tossed into a fire.
Note that the contents of the container may cause a subsequent chemical explosion, the effects of which can be dramatically more serious, such as a propane tank in the midst of a fire.

The quantity of heat absorbed or given off during transformation is called the heat of formation. Unsourced material may be challenged and removed. In such a case, to the effects of the mechanical explosion when the tank fails are added the effects from the explosion resulting from the released initially liquid and then almost instantaneously gaseous propane in the presence of an ignition source. High velocity, low angle fragments can travel hundreds or thousands of feet with enough energy to initiate other surrounding high explosive items, injure or kill personnel and damage vehicles or structures.
For this reason, emergency workers often differentiate between the two events. In other projects Wikimedia Commons Wikiquote. Many substances not ordinarily classed as explosives may xposion one, or even two, of these things.
