Answer 2

Heya dear user !!!

Here is your answer,

================================

A lighted candle has three zones =>

1. innermost zone : This zone consists of unburnt wax vapours given up by the molten wax. It is the coldest part of the flame.

2. Middle zone / Luminous zone : In this zone, a partial combustion of wax vapours takes place with the liberation of lot of energy. This energy partly decomposes the wax vapours into carbon particles. The luminous zone of the flame is hotter than dark inner zone and is yellow in colour.

3. Outermost zone / Non - Luminous zone : It is a zone of complete combustion of wax vapours and carbon particles, The air from the side of the flame mixes with unburnt wax vapours and carbon particles from the luminous zone and completely burns them to form carbon dioxide gas and water vapour. It is the hottest part of the flame.

================================
