ExplosionAn explosion is

caused by combustion and a creation of heat and an extremely rapid expansion of gases.ChemicalMechanical

Oxidizing AgentA substance

that supplies oxygen to a chemical reaction.Black powderNitroglycerin

DetonationAn extremely

rapid oxidation reaction accomplished be a violent disruptive effect and an intense high speed shock wave.

Black PowderA mixture of

materials that make a low explosive.Potassium nitrate

75%Carbon

15%Sulfur

Safety FuseA cord

containing a core of black powder used to a carry a flame at a uniform rate to an explosive charge.

Smokeless PowderSingle-Base

An explosive consisting of nitrocellulose.

Double-BaseAn explosive consisting of a mixture of nitrocellulose and nitroglycerin

DeflagrationA very rapid

oxidation reaction accompanied by the generation of a low-intensity pressure wave that can disrupt the surroundings.

Deflagration

Low Explosive

An explosive with a velocity of detonation less than 1,000 meters per second.

High ExplosiveAn explosive

with a velocity of detonation greater than 1,00 meters per second
