or other specialized knowledge.
Fact witness
A voluntary act on the part of the responsible person, in lawful
control of a property, and can be withdrawn at any time by that
person.

Combustible Liquid
As the room temperature rises, convection continues, but the
role of ________ increases rapidly and becomes the dominate
heat transfer mechanism.
Radiation
A visible change observed to liquid or solid materials that are
heated and undergo physical and chemical changes, the original
material is converted to gas.
Mass loss
Analysis of the _____ __ ____ is most reliable for evaluating
fire spread. This determines what portions of materials or
construction were exposed the longest to heat a source.
Depth of char
A solid phase burning process, which normally includes a
thermal decomposition step to create a char, followed by solid
phase burning of the char produced.
Smoldering
