How is temperature defined in fire science?

In fire science, temperature is defined as the degree of sensible heat, which is measured using a thermometer. This definition emphasizes the quantifiable aspect of temperature, allowing for an objective measurement of the thermal energy present in a substance. The concept of sensible heat refers to the heat that can be sensed or felt, and it plays a crucial role in fire dynamics, influencing flames, heat transfer, and the behavior of materials in a fire environment.

Understanding temperature as a measurable parameter is essential for investigating fires, as it provides vital information on how materials will behave when subjected to heat. It also helps in assessing the progression of a fire, the likelihood of ignition of various substrates, and the overall dynamics of heat release during combustion. This foundational knowledge supports fire investigators in analyzing fire scenes and determining the potential causes and effects of fire events.
