Different Types of Explosives
An explosive is something capable of exploding or tending to explode.
The energy released is used in firearms, blasting, and rocket
propulsion.
Explosives are substances that produces a rapid, violent reaction when
exposed to heat, a strong blow or a special detonator. During the
reaction, explosives give off large amounts of gases at high pressure.
The
powerful blast of energy released during an explosion gives explosives
many
commercial and military uses. Explosives let construction workers
clear
land away for building roads or buildings with little effort. They are
used in digging mines and to loosen the flow of oil deep beneath rock
in
oil wells. They blow away tunnels through mountains and send rockets
into
space. In war, explosives are used to damage cities, destroy ships and
airplanes, and kill enemy troops. As you see, explosives aren't always
used as harmless substances.
Explosives may be solids, liquids, or gases. However, all explosives
consist of a fuel and an oxidizer--a substance that supplies the
oxygen
needed to make the fuel burn. When the most powerful explosives
detonate,
a chemical reaction takes place very quickly (usually in less than a
millionth of a second). Liquids and solids change to hot gases that
expand
with a large blast of heat and pressure. The higher the pressure, the
more
powerful the explosion is.
There are four main types of chemical explosives--primary explosives,
high explosives, blasting agents, and low explosives.
Primary Explosives should be handled in small quantities. They are
very sensitive to heat, and even a s...

foundations for large buildings. It also has been used for demolition
in
warfare.
The main explosive in dynamite is nitroglycerin. It is mixed with
other materials--some explosive and some nonexplosive--and packed in
cylinders made of waxed paper or plastics.
Dynamite contains nitroglycerin and an absorbent, chemically
reactive mixture, such as wood pulp and sodium nitrate. It is the
oldest
type and has been replaced by ammonia dynamite for most uses.
Ammonia dynamite is more powerful, safer, and less expensive than
straight dynamite. It contains ammonium nitrate and produces fewer
toxic
fumes and cooler gases than other dynamites do. It is called a
permissible
explosive, which means that it can be used safely in mines where
extreme
heat could ignite dust or gas in the air.
After looking at the five steps in comprehensive incendiary investigation it looks like a form of scientific method used in many other areas of fire investigation. The five steps are fire scene investigation, assessment of investigative needs, formulation and evaluation of a strategy, implementation of strategic plan and presentation of formal investigation. The five steps, like the scientific method, they have a beginning, middle and end. After I go over the five steps then I will identify the methodology in securing the interview, identify the interviews I will need and I will list some question.
Ammonium nitrate, on its own, is relatively harmless in regards to explosives. Ammonium Nitrate is a secondary explosive; it requires a primary explosive for detonation. It is able to burn without detonating and can withstand shock in which primary explosives are unable to do When ammonium nitrate is mixed with fuel oil and detonated the results can be catastrophic. The Oklahoma City bombing of 1995 is evidence of the impact of a blast using ammonium nitrate and fuel oil, known as ANFO. Timothy McVeigh parked a van filled with ammonium nit...
Since man’s first experiences with fire we have longed to control it and we wished to will it to do our bidding. For very long we failed mostly, and we still do sometimes, but with the trials and experiments we have done and died doing, we succeed now, mostly. The first formula that is still written down of an “explosive or pyrotechnic composition” are the three examples of gunpowder in the 1044A.D. Chinese military guide Wujing Zongyao which showed a few uses of this powder they had experimented with for near a hundred years. The most used formula from it was approximately 50% KNO3, also known as Saltpeter in those times, and formally called Potassium nitrate today, ~25% S, Sulfur, and ~25% carbonaceous matter (mostly charcoal and compounds mixed with impure sulfur); the other formulas move the percentages for the KNO3 around 10-15%, S 5-10%, and carbonaceous 7-20% to adjust burn rates and usefulness in certain situations. The likely only reason gunpowder was ever invented was the Chinese’s wish to live long, and their many mixtures of elixirs, which was what gunpowder was intended to be used as (more-pyrotechnics.com). “Within 200 years China had several crude weapons, mostly huge iron or alternative metal barrels and maybe a wooden grip but with no aiming attachment. They also had very many types of fireworks using no telling how many formulae for devices ranging in size, color, and purpose. People in Europe hear of this powder and its power, and then slowly find out more“(more-pyrotechnics.com). Then by 300 years they had better arsenals, larger cannons that actually worked well, and better, lighter barrels. The Indians and Islamic nations have made use of this by now, neither surpassing China’s previous ones nor Europe’s futu...
Weapons and Artillery of World War II The result of World War II was affected by many different factors. One major factor which affected the war was the weapons and artillery used during the war. Since the beginnings of time, weapons have always been around. From swords and knives to nuclear weapons and missiles, weapons have evolved greatly over the years.
Cluster bombs are a bomb that has a bunch of missiles that on impact to wound or damage people and vehicles. They mean to hit many different areas at one time. Land mines are explosives that are on the ground or hidden so that soldiers cannot find them. They hide from view so that when someone steps on them ...
President Truman stood in the oval office full of many advisors, but was truly alone ready to make the hardest decision, which would change the world forever. Is dropping the bomb the right decision for the president to make?
In Module one, I learned that terrorism is a result of physical harm or deadly acts of force with the intent of a political outcome by the use of terror for coercion. There are various types of terrorism such as international terrorism and domestic terrorism. International terrorism occurs outside of the United States with a purpose to influence the policy of a government by intimidation. International and Domestic terrorism both involve violent acts dangerous to human life that violate federal and state laws. Domestic terrorism occurs within the United States with the intention of coercion or intimidation by way of mass destruction, etc. Some forms of terrorism include Improvised explosive devices (IED), kidnappings, suicide bombings and
To detonate one of these bombs, enough mass of plutonium or uranium must be provided to reach what is known as "critical mass." Critical mass is the mass at which the nuclear reactions going on inside the material can make up for the neutrons that are leaving the material through its outside surface. These materials are usually separated within the bomb so that critical mass cannot be reached until the bomb is ready to explode. Once the chemical reactions within the bomb begin, the neutrons released by each reaction hit other atoms and create more fission reactions until all the material is scattered, or completely exhausted. This process releases enormous amounts of energy in the form of extreme heat and a massive shock wave. These nuclear explosions, in addition to their pressure waves, high winds, and flash burns, produce deadly radiation that contaminates soil and water, and destroyed living matter.
“(A) any destructive device as defined in section 921 of this title (i.e. explosive device);
The developments of gunpowder and the cannon were the most important advances during the Middle Ages. If it weren't for these inventions, who knows how we would be fighting today, possibly still the wars of Ancient Rome. The development of gunpowder meant that soon the use of knights would be useless because of the projectile that could easily knock a knight off his horse, rendering him helpless. The gunpowder enabled this projectile. The development of the cannon goes hand-in-hand with the gunpowder. This invention enabled things to be projected by the use of gunpowder. This invention also stopped sieges, which ended the need of city-walls. The crude versions of these weapons were used during the Hundred Years War, between England and France. Eventually these inventions paved the way for the modern gun and other inventions like bombs. These developments were truly the most important things that came out of the Middle Ages.
The first gunpowder was black powder which is mainly saltpetre. Black powder is thought to be discovered in china. Without gunpowder we wouldn’t be able to protect our country or protect
Bombs and shells changed the scenery again. Missiles, so far generating their destructive forces solely from their momentum of mass and velocity, now carried explosive material to the target. The old flaming arrows already followed this principle.
Chemical Warfare is not the same as nuclear warfare, or the same as biological warfare. Chemical warfare involves using the deadly properties of chemical substances as weapons.Most weapons used in chemical warfare are considered to be“weapons of mass destruction” or, WMDs, and are not considered to be conventional weapons. Chemical warfare does not depend upon explosive force to neutralize targets; it depends on the chemical properties of a chemical agent weaponized. Defoliants are an example.They are used to kill off vegetation and deny its use of cover by the enemy. “Defoliants can also be used against agriculture and livestock to promote hunger and starvation but with protective equipment, and decontamination measures, the effects of defoliants can be neutralized.

Chaos, fear, and death. Those three words are what most people’s first thoughts are when they see the destructive offspring of either Biological or Chemical Weapons. These Weapons of Mass Destruction (also known as WMD’s) are actually considered the deadliest weapons of all time to not only humans but also to other animals, and plants. Biological and Chemical Warfare has become a major threat not only to the safety to the people of America, but also on the frontlines across the world but, that in order to fix these that the Biological and Toxin Weapons Convention and Chemical Weapons Convention could do is to make mandatory background checks for anyone who buys any additives that are in any Bio/ Chemical weapons, mandatory safety exercises, and make bans heavier on the use of these weapons in war.
The use of torture has become a prominent matter of dispute as we enter an age of the global war on terror. The debate on whether it has become morally permissible to torture terrorists is argued by many as the legitimacy of such actions are brought into question in a world where global terror is outstanding. With the use of the ticking time bomb scenario, some make a desirable case that in special circumstances, there is a right to torture individuals implicated is acts of mass violence. Yet many would still argue that there are an array of inconsistencies hidden within the ticking bomb scenario and there are no circumstances where torture can be morally permissible, no matter what the consequences may hold.
