1) Transfer of heat through direct contact between two objects or through contact with an intervening medium that transfers heat.

2) The ability to mix together.

3) Not capable of mixing together.

4) Radiant heat providing energy for continued vaporization.

5) Percentage of a substance in air that will burn once ignited.  Synonymous with Explosive Limit.

6) The amount of heat energy provided by one watt flowing for one second.

7) Flammable liquids that have an attraction to water.

8) Any liquid having a flash point below 100^oF and having a vapor pressure not exceeding 40psi absolute.

9) Generally considered the phase of the fire where sufficient oxygen and fuel are available for fire growth and open burning to a point where total involvement is possible.  Synonymous with Free-Burning Phase.

10) The ability of a substance to conduct an electrical current.

11) Unburned fuel left behind after a fire.

12) The range between the upper flammable limit (UEL) and lower flammable limit (LEL) in which a substance can be ignited.  Synonymous with Flammable Range.

13) An acid that contains carbon and will burn.

14) The space occupied by a substance.

15) Condition created by a sudden inflow of fresh air to an oxygen-deficient smoldering fire which creates an explosion.

16) A liquid's thickness or ability to flow.

17) First phase of the burning process where the substance being oxidized is producing some heat, but the heat has not spread to other substances nearby and the oxygen in air has not been significantly reduced.

18) Unburned superheated combustible gases released during the incipient or early steady-state phase that accumulate at ceiling level and are pushed, under pressure, away from the fire area and into uninvolved areas where they mix with oxygen and ignite once reaching their ignition temperature resulting in flames rolling across the ceiling.

19) Plane geometric figure in which the three sides of an equilateral triangle represent oxygen, heat, and fuel, the elements necessary to sustain combustion.

20) Substance that yields oxygen readily and may simulate the combustion of organic and inorganic matter.

21) Stage of fire at which all surfaces and objects within a space have been heated to their ignition temperature and flame breaks out almost at once over the surface of all objects in the space.

22) Situation in which heat is fed back to the fuel.
