What is explosive and its types?
explosive, any substance or device that can be made to produce a volume of rapidly expanding gas in an extremely brief period. There are three fundamental types: mechanical, nuclear, and chemical. A mechanical explosive is one that depends on a physical reaction, such as overloading a container with compressed air.
What are the different types of explosions?
There are three main types of explosions: chemical, mechanical and nuclear. Each type of explosion can be equally devastating and serious, causing unprecedented harm to the surrounding people, atmosphere and infrastructure.
What are the main effects of explosives?
The basic immediate effects of explosive weapons are: 1) a blast wave—a wave of pressure that radiates out from the detonation at high speed; 2) fragmentation—material is broken up and projected outwards from around the point of detonation, creating high-velocity fragments; and 3) heat—the detonation of explosives …
What is an explosion Class 8?
The type of combustion reaction that occurs with the evolution of tremendous amount of heat, light, gases and sound is known as Explosion. For instance, when we burn a cracker it bursts with the liberation of tremendous amount of heat, light, gases and sound. It is explosion.
What are the types of high explosives?
High Explosives – explosive materials that can be caused to detonate by means of a blasting cap. A few examples of high explosives would be boosters, detonators, dynamite, water gels/slurries, and emulsions.
What are two types of high explosives?
High explosives will be referred to Type E explosives, and there will be three sub-types in this group:
- 1 – blasting and bulk explosives (explosives used for commercial blasting applications or for their manufacture);
- 2 – perforating explosives (intended for use in the oil and gas well industry);
What are the characteristics of explosive materials?
EXPLOSIVES DEFINITIONS 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 do you mean by explosive substance?

What is the purpose of anexplosive?
Explosive. Such a device has some application in mining, where the release of gas from chemical explosives may be undesirable, but otherwise is very little used. A nuclear explosive is one in which a sustained nuclear reaction can be made to take place with almost instant rapidity, releasing large amounts of energy.
What is the difference between detdetonating explosives and Deflagrating explosives?
Detonating explosives, such as TNT and dynamite, are characterized by extremely rapid decomposition and development of high pressure, whereas deflagrating explosives, such as black and smokeless powders, involve merely fast burning and produce relatively low pressures.
