Answer 2

Combustion=rapid chemical combination of a substance with oxygen, involving the production of heat and light.

Ignition temperatur= The autoignition temperature of a substance is the lowest temperature in which it spontaneously ignites in normal atmosphere without an external source of ignition, such as a flame or spark.

Flame=A flame is the visible, gaseous part of a fire. It is caused by a highly exothermic reaction taking place in a thin zone. Very hot flames are hot enough to have ionized gaseous components of sufficient density to be considered plasma.
