Solution
A candle flame consists of three different zones. Each zone has different temperatures.
- The first zone is the outer zone: Due to complete combustion, the outer zone is blue. This zone is the hottest when compared to the other zones. This blue coloured zone is the non-luminous part of the flame.
- The second zone is the middle zone: The yellow coloured region which is the bright part of the flame is the middle zone. It is moderately hot and partial combustion of fuel takes place.
- The third zone is inner zone: The inner zone is dark and mostly consists of unburnt wax vapours.
