Answer 2

Explanation:

In a candle flame, a quarter of the energy created is released as heat.

A candle flame consists of three different zones. Each zone has different temperatures. Every zone has different colour and this will help us in understanding the temperatures of each zone.

The first zone is called the Outer zone

The second zone is called the Middle zone

The third zone is called as Inner zone

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. It is moderately hot and partial combustion of fuel takes place. The least hot region of the flame is present innermost. This inner zone is black due to the presence of unburnt wax vapours.
