what are the parts of a flame?

Answer 1

A flame is a plasma or an ionised gas, it is the product of a highly exothermic reaction for example combustion,a self-sustaining oxidation reaction, or nuclear fusion in the sun. In layman's terms, a flame could be said to be, for example, the visible part of a fire.

The color and temperature of the flame are dependent on the type of fuel involved in the combustion. For example when a lighter is held to a candle. This applied heat causes the fuel molecules to evaporate, in this state they can then react with oxygen, giving off enough heat in the exothermic reaction to sustain a consistent flame. The resulting increases in temperature tears apart some of the fuel molecules, forming various incomplete combustion products and free radicals. Sufficient energy in the flame will excite the electrons in these products, which results in the emission of visible light. As the combustion temperature increases, so does the energy of the electromagnetic radiation given off by the flame. This is why the hottest visible flame is in the blue/violet region of the visible spectrum.

Other oxidizers besides oxygen can be used. Hydrogen burning in chlorine produces a flame as well, producing gaseous hydrogen chloride (HCl). Other possible combinations are fluorine and hydrogen or hydrazine and nitrogen tetroxide.

Answer 2

The visible part of a flame is mostly the reaction of gases to the intense heat they are subjected to. A small part is plasma. There are all sorts of things going on in fire.

Answer 3

a flame or fire has heat fuel oxygen
remove one of the three parts and fire has nowhere to go
a flame as in a bunsen burner
needs fuel gas oxygen a luminous flame no air is yellow gives off soot, a non-luminous blue with oxygen or air
