Liquids (such as petrol and other fuels) and solvents in industrial products (such as paint, ink, adhesives and cleaning fluids) give off flammable vapour which, when mixed with air, can ignite or explode. The ease by which liquids give off flammable vapours is linked to a simple physical test called Flashpoint (ie.
What is the most explosive thing on earth?
Azidoazide azide is the most explosive chemical compound ever created. It is part of a class of chemicals known as high-nitrogen energetic materials, and it gets its “bang” from the 14 nitrogen atoms that compose it in a loosely bound state.
Can things explode without oxygen?
Because high explosives do not require oxygen (or any other co-reactant), they break down much more rapidly and are much more versatile than combustible materials. High explosives generally cannot be detonated by heat alone and so require a detonator to deliver either a shock wave or an electric charge.
Can a human survive a explosion?
The human body can survive blasts of sudden pressure of 20-40 psi, but it’s not the only thing receiving that pressure. The pressure radiates outward from the blast in all directions. When it leaves a vacuum behind it, air from the surrounding atmosphere moves in to fill that vacuum.
What can cause an explosion without fire?
Dust explosions can occur when any distributed combustible dust is present in high enough quantities in the atmosphere or another oxidizing gaseous media, such as pure oxygen. A fuel-air explosion occurs when fuel is the explosive ingredient in a blast resulting in dust clouds.
Can you make an explosive with sugar?
It’s easy to forget that sugar can be an explosive. In fact, it’s four times more powerful weight for weight than TNT. Forgetfulness here can have tragic consequences. In 2008, finely powdered sugar ignited at a refinery in Savannah, Georgia, causing a blast that claimed 14 lives.
What is a C-4 bomb?
Composition C4 is a plastic explosive substance used in military combat units for demolition. The active component of composition C4 is hexahydro-1,3,5-trinitro-1,3,5-triazine, also known as RDX (Royal Demolition Explosive).
Can you make C-4?
To make C-4 blocks, explosives manufacturers take RDX in powder form and mix it with water to form a slurry. They then add the binder material, dissolved in a solvent, and mix the materials with an agitator. They remove the solvent through distillation, and remove the water through drying and filtering.
Is C-4 stronger than TNT?
C4 explosives have more complete destructive power compared to TNT and the number of effective explosives required to destroy the concrete with the strength of fc = 229.31 kg / cm2 is 122 g.
Would a human body explode in space?
Humans don’t explode in space. Even though outer space represents a lack of air pressure, which usually counters the internal pressure in our bodies, our tissue is strong enough to handle the imbalance.
Would your blood boil in space?
In space, there is no pressure. So the boiling point could easily drop to your body temperature. That means your saliva would boil off your tongue and the liquids in your blood would start to boil. All that bubbly boiling blood could block blood flow to vital organs.
Would you freeze or burn in space?
Acute exposure to the vacuum of space: No, you won’t freeze (or explode) One common misconception is that outer space is cold, but in truth, space itself has no temperature. In thermodynamic terms, temperature is a function of heat energy in a given amount of matter, and space by definition has no mass.
Should you open your mouth during an explosion?
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.
Can you survive a nuclear bomb in a pool?
While the radiation from the initial detonation is setting everything nearby on fire, the surface of the water will harmlessly evaporate. Since the boiling point of water isn’t very high and the flash doesn’t last very long, the whole body of water will stay cool, even if it’s only a swimming pool.
Can you shoot down a nuke?
Short answer: It’s very unlikely. As you read above, causing a nuclear bomb to detonate requires a precise orchestration of events, without which the chain reaction does not initiate and the bomb doesn’t detonate.
Can sugar dust explode?
But when dust from high-energy substances, such as sugar, is allowed to accumulate in closed spaces and happens to ignite, it can cause an explosion. The U.S. Chemical Safety and Hazard Investigation Board invest- igated three major industrial explosions involving combustible powders.
Can natural gas explode?
Natural gas is only explosive when mixed in the air at a concentration between 5 and 15 percent. When it leaks into an enclosed space, like a basement, it can be a serious problem. And leaks that find their way into sewer lines also present potential hazards.
Can dust explosive?
Dust can collect on surfaces such as rafters, roofs, suspended ceilings, ducts, crevices, dust collectors, and other equipment. When the dust is disturbed and under certain circumstances, there is the potential for a serious explosion to occur. The build-up of even a very small amount of dust can cause serious damage.
What two chemicals will explode when mixed?
Peroxides (inorganic), when mixed with combustible materials, barium, sodium, and potassium, form explosives that ignite easily. Phosphorus (P), both red and white, forms explosive mixtures with oxidizing agents. White (also called yellow) P should be stored under water, in glass, because it is pyrophoric.
What two chemicals can start a fire?
When potassium chlorate and ordinary table sugar are combined, and a drop of sulfuric acid is added as a catalyst, the two react violently with each other, releasing large quantities of heat energy, a spectacular purplish flame, and a great deal of smoke.
Are marshmallows flammable?
Everyone who’s ever cooked marshmallows around a campfire knows they burn. So how can sugar explode? Though you may not normally think about it, one of sugar’s properties is that it is flammable.
Will C4 explode if you shoot it?
A block of C4 plastic explosives can withstand a rifle shot without exploding. You can even set one on fire without too much worry. That doesn’t mean a bomb made out of C4 or another less-sensitive explosive, like TNT, is impervious to gunshots.
Can C4 detonate underwater?
C4 is waterproof and may be used underwater if necessary. C4 is easily and reliably initiated by L1A2, or L2A2 detonators, detonating cord L5A1 or Detonating Cord Boosters (DCB).
What is in Semtex?
Semtex is based on PETN-RDX (Penaerythrite tetranitrate – Research Development Explosive), a plastic explosive formerly made by Explosia in the Czech Republic. It is a favourite explosive of terrorist groups, particularly PIRA, as only small amounts are needed for horrendous results.
What are the most powerful explosives?
Nitroglycerine, discovered in 1846, still remains the most powerful explosive in practical use.
