FINAL EXAM 2025 /2026 Q&A Updated and Graded A+|
What is the difference between the fire triangle and fire
tetrahedron? - ANSWER-The fire triangle illustrates the
three components needed for a fire while the fire
tetrahedron demonstrates the four components of a self-
sustaining fire.
The fire triangle, is the oldest and simplest model that
shows three elements necessary for combustion to occur,
OXYGEN, FUEL AND HEAT.
The fire Tetrahedron includes an uninhibited chemical
chain reaction to occur. The tetrahedron includes the
,chemical chain reaction to explain flaming or gas-phase
combustion).
is flaming combustion fast or slow? - ANSWER-
Combustion that results in a flame is very fast and is
called burning. Combustion can only occur between
gases.
heat is - ANSWER-the thermal kinetic energy needed to
release the potential chemical energy in a fuel. As heat
begins to vibrate the molecules in a fuel, the fuel begins a
physical change from a solid or liquid to a gas. The fuel
emits flammable vapors which can ignite and release
thermal energy. It then starts to heat other uninvolved fuels
converting their energy and spreading the fire.
, Temperature is the.. - ANSWER-measurement of heat.
The average kinetic energy in the particles of a sample of
matter.
increased heat-release-rate results in an - ANSWER-
increased heat transfer rate to an object (heat flux)
chemical energy is the - ANSWER-most common source
of heat in combustion reactions
the heat transfer from one point or object to another is part
of the study of thermodynamics. - ANSWER-
