Fire is a very rapid reaction in which:
Web• Deflagration is a very rapid combustion of particles of an explosive. The combustion begins at one or more points or on a surface and ‘burns’ at a very rapid rate through the material. The rate of reaction is subsonic or in other words below the speed of sound. WebFire: A rapid oxidation process, which is a chemical reaction resulting in the evolution of light and heat in varying intensities. The structure of the fire will change depending on how the process of combustion takes place. …
