Fires and explosions require three elements in order to occur (the ‘fire triangle’): oxygen, fuel and heat.
HMX is the most powerful high explosive produced in industrial quantities today. It is a relatively insensitive, temperature-stable and safe-to-handle high explosive that makes it useful in a variety of applications both in military and civilian end products.
It’s easy to forget that sugar can be an explosive. In fact, it’s four times more powerful weight for weight than TNT. … In 2008, finely powdered sugar ignited at a refinery in Savannah, Georgia, causing a blast that claimed 14 lives. Fortunately, under normal circumstances it takes a lot to make sugar explode.
They require an electrical spark, fuse, intense heat, or sharp blow to initiate their explosion. Secondary explosives are relatively insensitive to heat, shock, or friction and will normally burn rather than detonate if ignited in small quantities in the open air.
Many explosions occur when gases are exposed to a source of heat– such as fire, sparks, even static elec- tricity-or an increase in pressure. Explosions can also be caused by chemical reactions.
Explosions: Explosions can be the result of combustion, chemical reaction, or mechanical failure. For combustion or fire-related explosions, ARCCA engineers and fire investigators investigate the explosion much like a fire (i.e. explosion cause and explosion origin) using many of the same methodologies.
Fission weapons are commonly referred to as atomic bombs. Fusion weapons are also referred to as thermonuclear bombs or, more commonly, hydrogen bombs; they are usually defined as nuclear weapons in which at least a portion of the energy is released by nuclear fusion.
Nuclear bombs have had yields between 10 tons TNT (the W54) and 50 megatons for the Tsar Bomba (see TNT equivalent). A thermonuclear weapon weighing little more than 2,400 pounds (1,100 kg) can release energy equal to more than 1.2 million tons of TNT (5.0 PJ).
All explosions, regardless of their source, are characterized by a large release of energy, the production of gas molecules that expand quickly, and a rapid rate of reaction. Burning sugar—chemically known as sucrose (C12H22O11)—produces energy almost immediately.
Is Flour Combustible? So, can flour explode? As astonishing as it may sound, the fact is that flour dust is more explosive than gunpowder and 35 times more combustible than coal dust. However, it is not explosive in small, non-dispersed quantities.
Urea nitrate 1 (Fig. 1) is a powerful improvised explosive, fre- quently prepared and used by terrorists. It can be prepared quickly and easily by adding nitric acid to a cooled aqueous solution of urea (Scheme 1). The white precipitate thus formed is filtered, washed with cold water and dried in air.
The explosion is set off by an electrostatic spark. When the mixture ignites, the rapid increase in temperature brings about a huge increase in gas pressure. If the burning vapour were to be confined the resulting rise in pressure could destroy the chamber with a loud explosion.
It depends on the explosives. Some bomb materials are highly sensitive to impact. If you shoot a gun at a stick of dynamite, for example, there’s a good chance you’ll set it off. … If a bullet were to strike the detonator, it could easily set off the more volatile explosives stored inside.
Smell: Some explosive materials smell of marzipan or almonds. Noise: Ticking or hissing sounds may indicate the presence of an explosive device.
Explosions create waves of increased pressure, followed by negative pressure, which can be extremely damaging to ears and internal organs. Keeping ones mouth open is said to equalize pressure, therefore reducing internal damage.
Makeup experts combine either liquid latex or silicone with other chemicals to create a patch of skin that is either thick and leathery or soft and wrinkly. To make explosions or fires, they use miniature mod- els, which they blow up or burn. one of the paradoxes of fake snow is that it is better than the real thing.
Many astronomical objects such as novae, supernovae and black hole mergers are known to catastrophically ‘explode’. … But as long as the explosion doesn’t require oxygen, then it will work in much the same way in space as on Earth.
Explosion risk is most often defined as the product of the probability of an explosion and its expected consequence.
1. an expression used in text messages or e-mails signaling happiness or laughter. XD is an emoticon. X represents closed eyes while D stands for an open mouth.
In the final step, the DNT is nitrated to trinitrotoluene or TNT using an anhydrous mixture of nitric acid and oleum. … Bundle of TNT is a gear that was published in the avatar shop by Roblox on July 10, 2009. It can be purchased for 700 Robux.
J. Robert Oppenheimer
J. Robert Oppenheimer (1904-1967) was an American theoretical physicist. During the Manhattan Project, Oppenheimer was director of the Los Alamos Laboratory and responsible for the research and design of an atomic bomb. He is often known as the “father of the atomic bomb.”
1 A single nuclear weapon can destroy a city and kill most of its people. Several nuclear explosions over modern cities would kill tens of millions of people. Casualties from a major nuclear war between the US and Russia would reach hundreds of millions.
Flour explodes when its particles become suspended in the air in a dust cloud and are then ignited. The starch molecules burn relatively quickly, and it is their rapid expansion in the presence of heat that causes an explosion.
Granulated table sugar won’t explode by itself, but it can ignite at high temperatures, depending on the humidity and how quickly it’s heated up. … Extreme heat forces sucrose to decompose and form a volatile chemical called hydroxymethylfurfural, which easily ignites and sets the rest of the sugar on fire.
Urea nitrate is a fertilizer-based high explosive that has been used in improvised explosive devices in Afghanistan, Pakistan, Iraq, and various terrorist acts elsewhere in the world such as in the 1993 World Trade Center bombings.
