Volcanoes are a natural part of our landscape which experience explosions. Volcanoes erupt and create an explosion when magma rises up to the surface. This magma contains bubbles of gas, and when the pressure builds up, an explosive eruption occurs. The explosion can be destructive for those nearby and the surrounding atmosphere. In March , the Eyjafjallajokull volcano in Iceland exploded, marking its first eruption since Consequently, people were evacuated from the area and stayed in Red Cross shelters for temporary safety.
This explosion had huge effects upon the environment as ash from the explosion deposited dissolved iron into the North Atlantic, and the ash cloud also affected aeroplane traffic.
Chemical explosions are caused by either decomposition or combination reactions that produce large amounts of extremely hot gas, which expands rapidly and increases pressure. The large amount of hot gas essentially forms shock waves, creating an explosion which can have shattering effects. For example, gunpowder is one of the first chemical explosives which was used. Dynamite is also an example of a chemical explosive.
When dynamite is ignited, it will burn rapidly and release incredibly hot gas and an explosion. Mechanical explosions are caused when a high-pressure gas encounters a physical reaction, which consequently ruptures the container in which the gas is contained. Mechanical explosions involve the internal pressure of a contained gas becoming too high and expanding beyond the container's strength, resulting in the container bursting and the contained gas escaping, creating an explosion.
Nuclear explosions are caused by either fusion or fission reactions. Among the high explosives, primary explosives are those that ultrasensitive to heat, shock, or friction and provide the major ingredients found in blasting caps or primers used to detonate other explosives. Each of these molecules share the property of being highly strained structurally. Secondary high explosives are those chemicals that do not have to be contained to explode and are relatively stable and safe to handle.
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.
Dynamite, TNT, Semtex plastics are some common examples of this type of explosive. Huge Explosion! Funkyyyyyy YouTube. The process for examining evidence at the site of an explosion is very similar to the process followed at the scene of a fire. Ion Mobility Spectrometer. An Ion-mobility spectrometer IMS is an instrument that detects and separates ions in the gas phase. The technique passes absorbed gases through a tube using a carrier gas to promote flow.
The walls of the tube are electrified so that ions with greater charge are more attracted and move slower through the tube. Large ions also move more slowly through the tube.
A detector at the end of the tube recognizes the ions based on their charge and shape. The technique is heavily used by both military and law enforcement purposes; not only detecting explosives but also having use for identification of drugs.
