Candle flame
Candle flame
A candle flame can be divided into three zones depending on the amount of oxygen available:
1. The outer zone(blue) is the hottest part of the flame. In this zone, the wax vapours have enough oxygen to burn completely producing carbon dioxide and water. This zone emits very little light.
2. The middle zone (yellow) is less hot than the outer zone. Here, incomplete combustion of wax vapours (due to low oxygen) produces carbon particles( which glow, giving this zone its yellow colour) and carbon monoxide. This zone emits most light
.3.The inner zone(black) is the coolest part of the flame. In this zone, the wax vapours remain unburned as no oxygen is available. This zone is completely dark and emits no light.
