Answer 1

Answer:

A flame is the visible, gaseous part of a fire. It is caused by a highly exothermic chemical 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.

Answer 2

Answer:

⚫ $\huge\mathfrak\red{ flame}$

• flame may be defined as the region over which gases burn. when you burn a piece of paper or a wax candle of flame is produced.

$\fbox\pink{innermost zone}$

• this zone consist of unburnt wax vapour given off by the molten wax it is the coldest part of the flame.

$\fbox\blue{ middle zone or Luminous zone}$

• in this zone partial combustion of wax vapours takes place with the liberation of a lot of energy. this energy partially decomposes the wax vapour into carbon particle this Zone Of Flame is hotter than the dark inner zone it is yellow in colour.

$\fbox\green{ outermost zone or non Luminous zone}$

• it is a zone of complete combustion of wax vapour and carbon particles the air from sides of the flame mixes with unburnt wax vapours and carbon particles from the Luminous zone and burns them completely to form carbon dioxide gas. and water vapour it is the hottest part of the flame
