A flame (from Latin flamma) is the visible, gaseous part of a fire. It is caused by a highly exothermic chemical reaction made in a thin zone. [ 1 ] When flames are hot enough to have ionized gaseous components of sufficient density, they are then considered plasma .
The fire triangle or combustion triangle is a simple model for understanding the necessary ingredients for most fires. [1] The triangle illustrates the three elements a fire needs to ignite: heat, fuel, and an oxidizing agent (usually oxygen). [2] A fire naturally occurs when the elements are present and combined in the right mixture. [3]
A backdraft (North American English), backdraught (British English) [1] or smoke explosion is the abrupt burning of superheated gases in a fire caused when oxygen rapidly enters a hot, oxygen-depleted environment; for example, when a window or door to an enclosed space is opened or broken. Backdrafts are typically seen as a blast of smoke and ...
Flame coloring is also a good way to demonstrate how fire changes when subjected to heat and how they also change the matter around them. [1] [2] To color their flames, pyrotechnicians will generally use metal salts. Specific combinations of fuels and co-solvents are required in order to dissolve the necessary chemicals.
Rollover (also known as flameover) is a stage of a structure fire when fire gases in a room or other enclosed area ignite. [1] Since heated gases, the product of pyrolysis, rise to the ceiling, this is where a rollover phenomenon is most often witnessed. Visually, this may be seen as flames "rolling" across the ceiling, radiating outward from ...
