What is explosive explain?
1. An explosive substance is a solid or liquid substance (or mixture of substances) which is in itself capable by chemical reaction of producing gas at such a temperature and pressure and at such a speed as to cause damage to the surroundings. Pyrotechnic substances are included even when they do not evolve gases.
What are the four types of explosions?
There are chemical, mechanical and nuclear explosions which can take place and cause significant consequences for the surrounding people, atmosphere and infrastructure. It is important to know the differences between types of explosions, to understand how they occur and what this can mean.
What causes an explosion?
An explosion is caused by a rapid expansion of gas from a chemical reaction or an incendiary device. Signs of an explosion may be a very loud sound or a series of noises and vibrations, fire, heat, smoke, falling glass or debris.
How do explosives work?
A general theory of explosives is that the detonation of the explosives charge causes a high-velocity shock wave and a tremendous release of gas. The shock wave cracks and crushes the rock near the explosives and creates thousands of cracks in the rock. These cracks are then filled with the expanding gases.
What are the main chemicals used in explosives?
COMPOSITION OF BOMBS
Explosives Based on Nitrogen | Formula | Sum N + O |
---|---|---|

Octogen (HMX) | C4H8N8O8 | 81.06 |
Pentaerythritol tetranitrate (PETN) | C5H8N4O12 | 78.45 |
What are explosives made from?
Chemical composition A chemical explosive may consist of either a chemically pure compound, such as nitroglycerin, or a mixture of a fuel and an oxidizer, such as black powder or grain dust and air.
How do explosions work?
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.
