What is an explosive device?

Answer 1

Petard

Answer 2

Explosives are chemicals or compositions that rapidly decompose to form large volumes of gases, usually releasing lots of heat in the process.

There are two main types of explosives, high and low.

Low explosives deflagrate, or burn. Examples are gunpowder and flash powder. They burn at subsonic rates. They are heaving explosives, they push their surroundings.

High explosives detonate. Detonation is supersonic combustion powered by a self sustaining shockwave. Velocities of the shockwaves are very fast, for example TNT has a detonation velocity of 6100 meters per second. Examples of high explosives are TNT, nitroglycerin, PETN, RDX, and ANFO.

Answer 3

Explosions are when things go boom and shrapnel is spread outward. Imploding is much less awesome.

Imploding is much less awesome? How do you think black holes are created? I think that the implosion of a star into a black hole is probably the most awesome event in the universe! Ever!

Answer 4

An explosive is any element, compound or mixture that can be made to expand extremely rapidly, usually by exposing it to high heat, percussion, or a catalyst, usually producing a very damaging shock wave.

Answer 5

An unstable substance that can quickly decompose into other substances, releasing heat and/or expanding gasses extremely rapidly.
