Question

Different zones of a candle.​

Answer 1

Answer:

The flame of a candle has three zones.

Explanation:

Candles produce light by releasing heat. A candle flame consists of three zones. Each zone has different temperatures and colors.

The first zone is called the Outer zone

The second zone is called the Middle zone

The third zone is called the Inner zone

The outer zone is blue in color, due to complete combustion,. This zone is the hottest zone.

The middle one is in yellow color, which is the bright part of the flame. It is moderately hot and partial combustion of fuel takes place.

The least hot region of the flame is innermost zone. This inner zone is black in color due to the presence of unburnt wax vapors.

There are four types of

zone in a candle:

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

• Non-luminous Zone

• Luminous Zone

• Dark Zone

• Blue Zone

Additionally-

Let's know them in brief-

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

${\boxed {\boxed {\rm {\red {Non-luminous \: Zone} }}}}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

• This is the outermost zone of the candle flame.

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

• This zone is also called the zone of combustion.

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

• The wax vapours in this layer get more oxygen from surround air. Within that complete combustion takes place here.

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

${\boxed {\boxed {\rm {\red {Lluminous \: Zone} }}}}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

• This is the hottest part of the flame.

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

• This zone is the zone of partial or incomplete combustion.

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

• Here the supply of oxygen reduces and the carbon particles leave the flame as smoke and soot.

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

${\boxed {\boxed {\rm {\red {Dark \: Zone} }}}}$

• This is the innermost zone and this is the zone of no combustion.

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

• In this zone combustion doesn't take place as the area gets surrounded by the vapours of the combustible substance.

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

${\boxed {\boxed {\rm {\red {Blue\: Zone} }}}}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

• In this zone no oxygen is available for the burning to take place. The blue colour at the bottom is due to combustion of carbon monoxide. [See in the diagram]
