Chapter 16 (Fire and explosions) Flashcards
an offender`s pattern of operation
Modus operandi
The combination of oxygen with other substances to prodcue new substances
oxidation
The ability of potential of a system or material to do work
Energy
The rapid combination of oxygen with another substance, accompanied by the production of noticeable heat and light
combustion
The heat released during combustion
heat of combustion
The minimum temperature at which a fuel spontaneously ignites.
ignition temperature
The minimum temperature at which liquid fuel produces enough vapor to burn
flash point
The decomposition of solid organic matter by heat
pyrolysis
The entire range of possible gas or vapor fuel concentrations in air that a capable of burning
Flammable range
Combustion on the surface of a solid fuel int he absence of heat high enough to pyrolyze the fuel
glowing combustion
A fire caused by a natural heat producing process in the presence of sufficient air and fuel
Spontaneous combustion
any compound consisting of only carbon and hydrogen
hydrocarbon
A chemical/mechanical action caused by combustion and accompanied by the creation of heat and rapid expansion of gases
explosion
a substance that supplies oxygen to a chemical reaction
oxidizing agent
rapid oxidation reaction accompanied by a low-intensity pressure wave
deflagration
a rapid oxidation reaction accompanied by a violent effect and an intense high speed shock wave
detonation
An explosive with a velocity of detonation of less than 1,000 meters/second
low explosion
a mixture of potassium nitrate, carbon and sulfur
black powder
a cord containing a core of black powder, used to carry flame at a uniform rate to an explosive charge
safety fuse
an explosive consisting of nitrocellulose
smokeless powder(single)
explosive consisting of a mix of nitrocellulose and nytroglycerine
Smokeless powder(double)
explosive with a velocity of detonation greater than 1,000 meters/second
high explosive
A high explosive that is easily detonated by heat,shock or friction
primary explosive
A high explosive that is insensitive to heat, shock or friction
Secondary explosive
