What Does A Low-order Explosive Material Resemble?

What substance does a low-order explosive resemble when exposed to air and sunlight? dark brown rocks.

What is the property of low explosives?

What is the property of low explosives? Explanation: Low explosives are that material whose reaction rates are relatively slow and controllable. Examples: various propellants such as colloidal cellulose nitrate black powder charcoal etc.

What is the difference between high order and low order explosives?

Explosives are categorized as high order explosives or low order explosives. High order explosives have a strong supersonic pressure wave known as the blast wave or shock wave. Low order explosions have a subsonic explosion and lack the high order explosive blast wave.

What are the different types of explosives and their characteristics?

explosive any substance or device that can be made to produce a volume of rapidly expanding gas in an extremely brief period. There are three fundamental types: mechanical nuclear and chemical. A mechanical explosive is one that depends on a physical reaction such as overloading a container with compressed air.

What are the characteristics of explosives?

In general an explosive has four basic characteristics: (1) It is a chemical compound or mixture ignited by heat shock impact friction or a combination of these conditions (2) Upon ignition it decom- poses rapidly in a detonation (3) There is a rapid release of heat and large quantities of high-pressure gases …

What are low explosives?

Low explosives are mixtures of chemicals that burn very rapidly but subsonically (as opposed to supersonically) meaning that they “deflagrate.” They consist typically of fuel and an oxidizer. The black powder used in fireworks is one example of a low explosive.

What materials are explosive?

Examples of primary high explosives are:
  • Acetone peroxide.
  • Alkali metal ozonides.
  • Ammonium permanganate.
  • Ammonium chlorate.
  • Azidotetrazolates.
  • Azoclathrates.
  • Benzoyl peroxide.
  • Benzvalene.

What are the two types of high explosives?

There are two major categories high explosives and low explosives. High explosives are further divided into initiating or primary high explosives and secondary high explosives.

Can a grenade explode in space?

Yes it would explode. Most hand grenades are nowadays triggered chemically electrically or contain a fuze enclosed within the assembly so they don’t require atmospheric oxygen to ignite are watertight and otherwise more reliably go off at a preset time since activation.

Can a shockwave hurt you?

Gas-containing organs such as the lungs the middle ear and the gastrointestinal tract are most likely to receive the shock wave resulting in overpressure damage. Pathological manifestations include direct lung injury tympanic membrane rupture intestinal contusion and intestinal perforation.

Which definition describes explosive material?

An explosive substance is a solid or liquid substance (or mixture of substances) which is in itself capable by chemical reaction of producing gas at such a temperature and pressure and at such a speed as to cause damage to the surroundings.

What are the most widely used low explosives?

Consider for instance black powder the most primitive form of gunpowder and the quintessential low explosive. In black powder charcoal and sulphur are the fuel and postassium nitrate (KNO3) is the oxidizing agent.

What are the 3 categories of high explosives?

High explosives are divided into three main categories Primary (or Initiating) High Explosives Secondary High Explosives Boosters and Secondary High Explosives Main Charge.

What are the 3 characteristics of all explosions?

What are three characteristics of all explosions? The three characteristics are a large release of energy production of quickly expanding gas molecules and a rapid reaction rate.

Which is the most widely used low explosive quizlet?

The most commonly used low explosives are black powder and smokeless powder. Black powder is a mixture of charcoal sulfur and potassium nitrate.

What is dynamite made of?

Dynamite is an explosive made of nitroglycerin sorbents (such as powdered shells or clay) and stabilizers. It was invented by the Swedish chemist and engineer Alfred Nobel in Geesthacht Northern Germany and patented in 1867. It rapidly gained wide-scale use as a more powerful alternative to black powder.

Is pyrotechnics a low explosive?

Pyrotechnics together with explosives and propellants make up the trio of high-energy materials. The distinction between these materials is associated with the nature of the combustion process.

How do low explosives react?

Low explosives change into gases by burning or combustion. These are characterized by deflagration (burning rapidly without generating a high pressure wave) and a lower reaction rate than high explosives.

Is gunpowder a low explosive?

Gunpowder is classified as a low explosive because of its relatively slow decomposition rate and consequently low brisance. Low explosives deflagrate (i.e. burn at subsonic speeds) whereas high explosives detonate producing a supersonic shockwave.

What are flammable materials?

Flammable materials are the ones that are ignited or flame immediately when contacting with fire or high temperature in the air and continue to burn or slightly flame when leaving fire such as plywood fiberboard wood and foil.

What is the most powerful eXplosive material?

PETN. One of the most powerful explosive chemicals known to us is PETN which contains nitro groups which are similar to that in TNT and the nitroglycerin in dynamite. But the presence of more of these nitro groups means it explodes with more power.

What is the most explosive substance?

Azidoazide azide

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. This material is both highly reactive and highly explosive.

Which definition describes explosive material quizlet?

an explosive. An explosive is a chemical or mixture of chemicals that react violently and produce an explosion. Accelerants are chemicals used to make a fire burn hotter/faster than a natural fire.

What does TNT stand for?


trinitrotoluene (TNT) a pale yellow solid organic nitrogen compound used chiefly as an explosive prepared by stepwise nitration of toluene.

How does an explosion in space look like?

An explosion in space would realistically look like a brief spherical burst of light moving outwards as well as a discharge of energy and material from the exploding object (energy and light can both travel in a vacuum).

Can you feel a shockwave in space?

A ‘shock wave’ is the disturbance of material that’s created when a wave moves through a medium at greater than the local speed of sound. Provided there is a ‘medium’ of sufficient density through which a shock wave can travel there is no reason why shock waves can’t form in space.

Is fire possible in space?

Fires can’t start in space itself because there is no oxygen – or indeed anything else – in a vacuum. Yet inside the confines of spacecraft and freed from gravity flames behave in strange and beautiful ways. They burn at cooler temperatures in unfamiliar shapes and are powered by unusual chemistry.

Why do 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 lightning create shockwaves?

When lightning occurs it heats the air surrounding its channel to that same incredible temperature in a fraction of a second. Like all gases when air molecules are heated they expand. … When lightning strikes a shock wave is generated at each point along the path of the lightning bolt.

What is an explosive shockwave?

In simpler terms a blast wave is an area of pressure expanding supersonically outward from an explosive core. … It has a leading shock front of compressed gases. The blast wave is followed by a blast wind of negative gauge pressure which sucks items back in towards the center.

Which category of high explosive is much less sensitive than primary explosives is more commonly used as the main charge and is designed to withstand handling quizlet?

In general secondary explosives are much less sensitive than primary explosives. They are more commonly used as the main charge and are designed to withstand handling. Examples include TNT C-4 and dynamite.

What is the scientific definition of an explosion?

An explosion is defined as the rapid increase in volume and release of energy in an extreme manner. … Bodurtha explains in his book “Industrial Explosion Prevention and Protection ” “an explosion is the result not the cause of a rapid expansion of gases. It may occur from physical or mechanical change.”

What is considered a Class 1 explosive?

341.11 Class 1 Divisions
