what is anything that occupies space?

Matter

What is a chemical reaction between two or more materials that changes the materials and produces heat,flame, and toxic smoke?

Exothermic Heat Reaction

What is a chemical reaction in which a substance absorbs energy?

Endothermic Heat Reaction

What is an exothermic chemical reaction that is a self-sustaining process of rapid oxidation of a fuel, that produces heat and light?

Combustion

What is the model of the four elements/conditions required to have a fire, that includes fuel, heat, oxygen and chemical?

Fire Tetrahedron

What is stored energy that can be released in the future to preform a task called?

Potential Energy

What is the energy possessed by a moving object?

Kinetic Energy

What is the temperature at which an element will ignite by itself?

Autoignition Temperature

What is the name of the physical flow of heat from one body to another through contact?

Conduction

What is the transfer of heat by the movement of heated fluids or gases, usually in an upward direction?

Convection

What is the transfer of heat from a hotter body to a colder one usually though intervening space through waves like infrared, radio or X-rays?

Radiation

What is the fuel that is being oxidized or burned during combustion?

Reducing Agent

What is the weight of a substance in comparison of the equal volume of water at a specific temperature?

Specific Gravity

What is a process of evolution that changes a liquid into a gaseous state? The rate of this depends on the temperature.

Vaporization

What is the minimum temperature at which a liquid fuel produces enough vapor to ignite near the surface?

Flash Point

What is the temperature at which a liquid fuel produces significant vapors to sustain combustion?

Fire Point

What is a material that is capable of being mixed?

Miscible

What is the degree at which a solid,liquid or gas dissolves in a solvent (usually water)?

Solubility

The range between the upper and lower fire limit is called what?

Flammable range

What is a colorless, odorless, dangerous gas ( both toxic and flammable) that is formed by the incomplete combustion of fuel?

Carbon Monoxide (CO)

What is a colorless, odorless gas that nether supports combustion nor burns (used in class B fires as an extinguisher)?

Carbon Dioxide

What is the name of the phenomenon that occurs when mixtures of alkaline-based chemicals and certain cooking oils come into contact resulting in the formation of a soapy film?

Saponification

What is the first stage of the burning process?

Incipient Stage

What is the early stage of a fire when fuel and oxygen are virtually unlimited?

Growth Stage

What is the layering of smoke that occurs in a confine space called?

Thermal Layering

What is it called when gases are super heated in a confined space and oxygen is introduced creating a rolling effect?

Rollover

What is the stage in the fire at which all suffices have been heated to their ignition leading to a almost simutanius ignition?

Flashover

What is the name of the stage at which the fire is releasing the maximum amount of energy?

Fully Developed Stage

What is the name of the stage in the fire at which the fuel is burned and the energy is diminishing?

Decay

What is the rapid burning of super heated gases ( usually resulting in a explosive force when oxygen is introduced) called?

Backdraft
