Ignition Temperature - Lowest temperature at which a substance can sustain combustion in air or oxygen at a specified pressure. Incandescence - Emission of light by a substance due to its high temperature. Induction Period - Time required by combustibles before oxidation and burning can proceed independently of heat or energy input. Inerting Agent - Inert subestance like nitrogen or helium which can prevent formation if ignitable mixtures. Inhibition - Reduction of a fire or flame by the introduction of a chemical which interferes with the flame reactions.
Examples are freons and sodium bicarbonate.
Isothermal Process - Physical or chemical process without a temperature change. Jet Fuels - Jet aircraft fuels can be classed as low or high volatility petroleum mixtures. Jet A is very similar to Jet A-1. The commercial fuels in the US are not required to have the anti-static additive and generally do not have the additive. Kindling Temperature - The lowest temperature at which a substance ignites.
