Bunsen burner and candle flame
A flame is a region where a gas emits light because of the high temperature.
Burning, i.e. combustion, needs oxygen gas, is exothermic process and has reaction products are carbon dioxide and water.
Spontaneous combustion does not need external heat energy to start it, e.g. white phosphorus in air.
Combustible substances catch fire easily, e.g. paper.
You can smother a flame to cut off the oxygen gas supply and put out the fire.
Water is used to put out fire because it reduces the temperature of substances below its ignition point.
However, the temperature of burning oil is too high for an oil fire to be extinguished by water.
Most fire extinguishers either reduce the ignition temperature or cut off the oxygen gas supply.
