Fire Behavior IFSTA Ch 5 UPDATED
ACTUAL Exam Questions and CORECT
Answers
Combustion - CORRECT ANSWER - A chemic process of oxidation that occurs at a rate fast
enough to produce heat and usually light in the form of either a glow or flame
Fire - CORRECT ANSWER - A rapid oxidation process, which is a chemical reaction
resulting in the evolution of light and heat in varying intensities
Heat - CORRECT ANSWER - A form of energy characterized by vibration of molecules and
capable of initiating and supporting chemical changes and changes of state
Temperature - CORRECT ANSWER - Measure of a material's ability to transfer heat energy
to other objects; the greater the energy, the higher the temperature
Fuel - CORRECT ANSWER - A material that will maintain combustion under specified
environmental conditions
Oxidizer - CORRECT ANSWER - Any material that readily yields oxygen, or other oxidizing
gas, or that readily reacts to promote or initiate combustion of combustible materials
Matter - CORRECT ANSWER - Anything that occupies space and has mass
Physical change - CORRECT ANSWER - This occurs when a substance remains chemically
the same but changes in size, shape, or appearance
Chemical change/reaction - CORRECT ANSWER - This occurs when a substance changes
from one type of matter into another, such as two or more substances combined to form
compounds
, Energy - CORRECT ANSWER - Capacity to perform work; occurs when a force is applied to
an object over a distance or when a chemical, biological, or physical transformation is made in a
substance
Oxidation - CORRECT ANSWER - Chemical process that occurs when a substance combines
with an oxidizer such as oxygen in the air; a common example is the formation of rust on metal
Potential energy - CORRECT ANSWER - Stored energy possessed by an object that can be
released in the future to perform work once released
Kinetic energy - CORRECT ANSWER - The energy possessed by a body because of its
motion
Types of energy - CORRECT ANSWER - Chemical, thermal, mechanical, electrical, light,
nuclear, sound
Exothermic reaction - CORRECT ANSWER - Chemical reaction that releases thermal energy
or heat
Endothermic reaction - CORRECT ANSWER - Chemical reaction that absorbs thermal
energy or heat
Pyrolysis - CORRECT ANSWER - The chemical decomposition of a solid material by
heating. Pyrolysis often precedes combustion
Vaporization - CORRECT ANSWER - Physical process that changes a liquid into a gaseous
state; the rate of vaporization depends on the substance involved, heat, pressure, and exposed
surface area
Ignition - CORRECT ANSWER - The process of initiating self sustained combustion
