Middle zone of flame
Explanation:
There are three zones in a flame. For example, let's take a candle flame. It consists of three different zones. Each zone has different temperatures and different colours. Due to complete combustion, the outer zone is blue in color and it is the hottest. The yellow color 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 luminescence is caused by the incomplete combustion. The least hot region of the flame is present innermost. This inner zone is black in color due to the presence of unburnt wax vapors.
