IAAI-CFI Definitions Questions with Correct
Answers
Joule
The preferred SI unit of heat, energy, or work. A Joule is the heat produced when 1 ampere is
passed through a resistance of 1 ohm for 1 second, or its the work required to move a distance
of 1 meter against a force of 1 newton. 4.184 joules in a calorie. 1055 joules in a BTU. A watt
is a joule/second.
Watt
Unit of power, or rate of work, equal to 1 joule per second, or the rate of work represented by
a current of 1 amper under the potential of 1 volt.
Scientific Method
Recognized the need
Define the problem
Collect Data
Analyze Data
Develop Hypotheses (Inductive Reasoning)
Test Hypotheses (Deductive Reasoning)
Select final hypothesis
How can a hypothesis be tested
Physically by conducting experiments
Analytically by applying scientific principles
Referring to scientific research
, Any hypothesis that is incapable of being tested either physically or analytically is
considered _______________?
Invalid hypothesis
Expectation Bias
When an investigator reaches a premature conclusion without having examined or considered
all of the relevant data.
Confirmation Bias
When the investigator tries to prove the hypothesis, instead of disprove.
What is the Investigators Goal?
Origin and Cause, fire spread, and responsibility for the incident.
Level of certainty greater than 50%
Probable
Level of certainty less than 50%
Possible
At what level of certainty must be reached in order to render an opinion?
Probable
Court terminology for how certain an investigator is?
Within a reasonable degree of fire investigative certainty.
