fire
a rapid chemical process that usually produces heat and light.
fuel
form of energy
types of energy
chemical, electrical, and nuclear
chemical energy
energy created by a chemical reaction
endothermic reaction
absorbs heat
exothermic reaction
produces heat
electrical energy
energy that produces heat while traveling through a wire or another conductive material
nuclear energy
energy produced by splitting the nucleous of an atom into two smaller nuclei or by combining two smaller nuclei into one large nucleous
3 factors of fire
heat, fuel, oxygen
oxidizer
Any material that readily yields oxygen or other oxidizing gas, or that readily reacts to promote or initiate combustion of combustible materials.
combustion
combining a substance with oxygen to produce heat and light
smoke
a toxic by product
heat
A form of energy characterized by vibration of molecules and capable of initiating and supporting chemical changes and changes of state.
temperature
measure of a material's ability to transfer heat energy to other objects
matter
anything that takes up space and has mass
kinetic energy
The energy possessed by a body because of its motion.
potential energy
stored energy possessed by an object that can be released in the future to perform work once
Pyrolisis
the change from a solid fuel to a gas
Vaporization
the change from a liquid to a gas
Fire Tetrahedron
represents fuel, heat, oxygen, and self-sustaining chemical chain reaction.
kinetic energy transfer
moves from high-temperature to low-temperature substances
arcing
method of electrical energy that occurs when a high-temperature luminous discharge crosses a gap
convection
heat transfer that occurs through movement of hot smoke and fire gases
conduction
method of heat transfer that occurs when a material is heated as the result of direct contact with a heat source
radiation
method of heat transfer that can become the dominant mode as the fire grows in size
