What elements can cause a explosion?
Fires and explosions require three elements in order to occur (the ‘fire triangle’): oxygen, fuel and heat.
What causes natural explosions?
Natural 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.
How can ammonium nitrate cause explosion?
Ammonium nitrate prills provide a much more concentrated supply of oxygen than the air around us. At high enough temperatures, however, ammonium nitrate can violently decompose on its own. This process creates gases including nitrogen oxides and water vapour. It is this rapid release of gases that causes an explosion.
What is the most explosive element on earth?
class
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.
What can cause an explosion without fire?
Gas explosions can occur for a number of reasons including faulty appliances or equipment, a leak, or improper usage of a gas appliance. Gases are chemical substances, that when kept in an unstable environment or are exposed to an ignition source such as heat or fire, have to potential to explode.
What is 33 on the periodic table?
Arsenic
Arsenic, atomic number 33 lies in between phosphorus and antimony in group 15, the so called Nitrogen group of the periodic table.
How do scientists study asteroids?
The Hubble Space Telescope and ground-based radar observatories also contribute regularly to our understanding of asteroids. Several more missions, including NASA’s Psyche and Lucy, missions are in development to keep exploring these small worlds. Scientists also use ground-based radar to explore nearby asteroids whenever possible.
How do you find the post-explosion velocity of two objects?
If the exploding system includes two objects or two parts, this principle can be stated in the form of an equation as: If the masses of the two objects are equal, then their post-explosion velocity will be equal in magnitude (assuming the system is initially at rest).
What is it called when a meteor hits the ground?
When a meteoroid survives its trip through the atmosphere and hits the ground, it’s called a meteorite. Several meteors per hour can usually be seen on any given night. When there are lots more meteors, you’re watching a meteor shower.
What percentage of meteorites are made from asteroids?
Of these, 99.8 percent come from asteroids. The remaining small fraction (0.2 percent) of meteorites is split roughly equally between meteorites from Mars and the Moon. The over 60 known Martian meteorites were blasted off Mars by meteoroid impacts. All are igneous rocks crystallized from magma.
