1. explosives

   An explosive (or explosive material) is a reactive substance that contains a great amount of potential energy that can produce an explosion if released suddenly, usually accompanied by the production of light, heat, sound, and pressure. An explosive charge is a measured quantity of explosive material, which may either be composed solely of one ingredient or be a mixture containing at least two substances. The potential energy stored in an explosive material may, for example, be chemical energy, such as nitroglycerin or grain dust pressurized gas, such as a gas cylinder, aerosol can, or BLEVE nuclear energy, such as in the fissile isotopes uranium-235 and plutonium-239Explosive materials may be categorized by the speed at which they expand. Materials that detonate (the front of the chemical reaction moves faster through the material than the speed of sound) are said to be "high explosives" and materials that deflagrate are said to be "low explosives". Explosives may also be categorized by their sensitivity. Sensitive materials that can be initiated by a relatively small amount of heat or pressure are primary explosives and materials that are relatively insensitive are secondary or tertiary explosives. A wide variety of chemicals can explode; a smaller number are manufactured specifically for the purpose of being used as explosives. The remainder are too dangerous, sensitive, toxic, expensive, unstable, or prone to decomposition or degradation over short time spans. In contrast, some materials are merely combustible or flammable if they burn without exploding. The distinction, however, is not razor-sharp. Certain materials—dusts, powders, gases, or volatile organic liquids—may be simply combustible or flammable under ordinary conditions, but become explosive in specific situations or forms, such as dispersed airborne clouds, or confinement or sudden release.

1. explosives

   Substances the elements of which under certain conditions suddenly undergo a chemical rearrangement into gases, giving rise to great pressures on surrounding bodies. Modern writers recognize two different kinds of explosions,—explosions of the 1st order, or detonations, and explosions of the 2d order, or rapid combustions. Detonating explosions are practically instantaneous. The explosion is supposed to be propagated by a vibration throughout the mass. Ordinary explosions are propagated by inflammation. Gunpowder, which may be taken as a type of explosives of the 2d order, burns at a certain rate, depending upon the density. When a charge is fired the inflammation spreads from the point of ignition to all parts of the charge,—each grain is successively enveloped and burned from surface to centre. The velocity of inflammation is the greater in proportion to the degree of confinement from the increased tension of the gases. The velocity of combustion is the rate at which the solid grains are burned. It is measured by the distance passed over by the burning surface (the line being taken perpendicular to the surface) in the unit of time. Time thus enters into the explosion of gunpowder and gives it its peculiar value as a ballistic agent.

Examples of Explosives in a Sentence

1. Home Minister Safaraz Bugti:

   It was a judge's car that was passing, but I believe it was the police who were the target, it was a remote-controlled device with 3-4 kg of explosives ... I think these kinds of cowardly acts will not reduce our morale.

2. Jerry Guilbert:

   Before we send humans in to clear a building or check that critical infrastructure site for IED contamination, one of things that we'll do is bring these specially-trained mine detecting dogs up to sniff the perimeter, determine if there are explosives in that building and based on where the dogs may be indicating, find out where in the building perhaps do we think those explosive hazards are.

3. Regina Lopez:

   Open-pit mining as in the use of explosives is horrific for the environment. It's a cheap way to extract. And for the top most country vulnerable to climate change it's madness to even consider it, we must stop killing our future for the interests of a few.

4. Olli Heinonen:

   We see that the buildings are surrounded by berms; they are a distance from each other. This is a typical design for a site that works with high explosives, i think there are serious questions to be asked [of] the Iranian government. Most likely IAEA should have access to this site.

5. Sanjay Dubey:

   He is on the run. One of his accomplices has already been arrested. He has been charged under the Explosives Act.
