Explosion
An explosion is a rapid expansion in volume associated with an extremely vigorous outward release of energy. Gunpowder was the first explosive to be invented and put to use. Chemical explosions often initiated by an electric spark or flame in the presence of oxygen. Accidental explosions may occur in fuel tanks, rocket engines, etc.
About Explosion in brief
An explosion is a rapid expansion in volume associated with an extremely vigorous outward release of energy. Most natural explosions arise from volcanic or stellar processes of various sorts. Explosions can also occur outside of Earth in the universe in events such as supernovae. Gunpowder was the first explosive to be invented and put to use. Other notable early developments in chemical explosive technology were Frederick Augustus Abel’s development of nitrocellulose in 1865 and Alfred Nobel’s invention of dynamite in 1866. Chemical explosions often initiated by an electric spark or flame in the presence of oxygen. Accidental explosions may occur in fuel tanks, rocket engines, etc. A high current electrical fault can create an ‘electrical explosion’ by forming a high energy electrical arc which rapidly vaporizes metal and insulation material. Also, excessive magnetic pressure within an ultra-strong electromagnet can cause a magnetic explosion. The bursting of a sealed or partially sealed container under internal pressure is often referred to as an explosion.
Examples include an overheated boiler or a simple tin can of beans tossed into a fire. 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. A nuclear weapon is a type of explosive weapon that derives its destructive force from nuclear fission or from a combination of fission and fusion. As a result, even a nuclear with a small yield is significantly more powerful than the largest conventional explosives available, with a single weapon capable of destroying an entire city. If a grenade is thrown in mid air during the explosion, the blast will be 360° in the direction of the blast. In contrast, there is no large differential in pressure and no greater heat for a fire in a fireplace.
