False
All of the following are examples of mechanical heat sources except ____?
Electromagnetic induction
All of the following are measures of heat energy except ____?
Fahrenheit
All of the following are warning signs of backdraft except ____?
Flames emerging rom doors and windows.
All of the following are warning signs of flashover except what?
Smoke churning in window glass
Conditions that will cause a static electricity discharge include the following except ___?
Contact and separation between similar solids.
An ignitable liquid must be atomized in order to burn. T/F?
False
Factors that affect the rate in which a fire will grow include all of the following except ____?
The ambient temperature outside the fire area
Name the fire phase described: Fire is affected by the amount of oxygen, fuel, space, and insulation of the ceilings and walls.
Growth
Name the fire phase described: Fire is virtually free burning and has plenty of fuel?
Fully developed
Name the fire phase described: Fuel package has been mostly consumed and heat release rate drops.
Decay
Name the fire phase described: Heat generated from the ignition now begins to cause heat transfer to surrounding combustibles.
Growth
Name the fire phase described: In most cases, the fire is small and limited.
Ignition
Name the fire phase described:Small pockets of fire may still exist as the fuel slowly moves to the point of total consumption.
Decay
Oil-soaked rags, discarded and reading self-ignition temperature are an example of ___?
Exothermic reaction
The amount heat generated by electrical means depends on ____?
The amount of electricity flowing through the conductor, the amount of resistance in the conductor, and the density of the conductor.
The amount of heat that a substance absorbs as the temperature of the substance increases is called ___?
Specific heat
The danger of backdraft increases dramatically as oxygen levels drop below ___?
16%
The latent heat of vaporization is ____?
The amount of heat that is absorbed by a liquid that passes to a gaseous form.
What are the two forms of nuclear energy?
Fission and fusion
Vapor density is the comparison of the density of a given vapor or the fas to the density or ____?
Air
Which choice is not part of the fire tetrahedron?
Extinguishing agent
