Question

Label the various zones of candle flame and answer the following questions
1.
The hottest part of the flame
2.
Unburnt wax - vapours are found in which part of the flame?​

Answer 1

Answer:

A candle flame has 3 parts - innermost zone, middle zone and outer zone Innermost Zone (Dark).

1) Due to complete combustion, the outer zone is blue. This zone is the hottest in temperature when compared to the other zones. This blue coloured zone is the non-luminous part of the flame. The yellow colour region which is the bright part of the flame is the middle zone.

2) The innermost zone of a candle flame will contain unburnt vapour of wax. The luminous zone of a candle will contain very hot carbon particles. The innermost zone of a candle near the molten wax will contain unburnt wax vapour rising from it due to the heat produced from the candle flame.
