What does an explosion give off?

An explosion is a rapid expansion in volume associated with an extremely vigorous outward release of energy, usually with the generation of high temperatures and release of high-pressure gases. Supersonic explosions created by high explosives are known as detonations and travel through shock waves.

How does an explosion destroy things?

Most damage comes from the explosive blast. The shock wave of air radiates outward, producing sudden changes in air pressure that can crush objects, and high winds that can knock objects down.

Why do explosions break things?

The explosive breaks down chemically, and a great quantity of heat is released. In an instant, oxygen reacts with other elements such as carbon and hydrogen. The lightning-like expansion of gases produces a shock wave that slams against surrounding surfaces and blasts objects from its path.

What are the products of an explosion?

Volume of products of explosion The most widely used explosives are condensed liquids or solids converted to gaseous products by explosive chemical reactions and the energy released by those reactions. The gaseous products of complete reaction are typically carbon dioxide, steam, and nitrogen.

Why do nukes detonated in the air?

In nuclear warfare, air bursts are used against soft targets (i.e. lacking the hardened construction required to survive overpressure from a nuclear explosion) such as cities in countervalue targeting, or airfields, radar systems and mobile ICBMs in counterforce targeting.

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 do explosions happen for kids?

People make explosions mostly by using chemical explosive materials. A chemical explosion starts pressure waves in the medium where it happens. Explosions are categorized as deflagrations if the pressure waves are subsonic and detonations if they are supersonic.

Can u randomly explode?

Summary. Explosions never happen at random, they have their exact laws. And sometimes they need very little – high dust concentration, turbulence and ignition source, often spontaneous combustion. The highest risk of explosion primarily threatens factories, where they work with dust in any way.

What height do nukes detonate?

Nuclear weapons The air burst is usually 100 to 1,000 m (330 to 3,280 ft) above the hypocenter to allow the shockwave of the fission or fusion driven explosion to bounce off the ground and back into itself, creating a shockwave that is more forceful than one from a detonation at ground level.

What happens to a blast wave when a bomb explodes?

Blast wave: When a bomb explodes, the area around the explosion becomes overpressurized, resulting in highly compressed air particles that travel faster than the speed of sound. This wave will dissipate over time and distance and will exist only for a matter of milliseconds. This initial blast wave inflicts the most damage.

What are the effects of an explosion?

Fire and heat: The explosion may also create a fireball and high temperatures, which will result in burns on a human body or even cause secondary fires or explosions, depending on whether any other fuel sources or flammable materials are located near the blast.

How does an a bomb cause damage?

A bomb causes damage in several different ways, depending on the point at which the explosion impacts. These different points include the blast wave, shock waves, fragmentation, heat and the blast wind.

What happens if your character is near an explosion?

Unless your characters cause the explosion themselves, or unless it’s the result of a fire, etc., it’s very likely going to take them by surprise. If they’re near the blast, they may be at least temporarily deafened and a little disoriented. The explosion of high explosives sends out a shock wave.
