Middle zone. Three zones, for example, are apparent in the Bunsen burner flame: an inner zone of unburned gas; a middle zone called the reduction zone or reducing flame, since the supply of oxygen is deficient and the oxygen is therefore removed from an oxide placed in it; and an outer, or oxidizing, zone. The candle also symbolizes consumptive power, elemental magic and transformation. View Answer. If you look closely, you’ll notice that the candle flame isn’t the same uniform color. Q22: Explain different zone of a candle flame with a diagram. Answer: The innermost zone is the dark zone. Give details of the conditions in each zone.

The wax is then vaporized by the flame and burns. Outermost zone or non luminous zone This is called the outermost zone or the non luminous zone of a candle flame hair complete combustion takes place it is the hottest part of a candle flame 2. 3. A candle's flame can be divided into several zones: Zone 1: Non-Luminous zone - There is not enough oxygen for the fuel to burn. There are several "zones" within a non-luminous flame, and each zone has a different temperature. That’s because candle flames have several different zones of heat. In a candle the heat from this zone melts nearby wax to allow for wicking. Name the different zones of a candle flame. There are three different zones of a candle flame : 1.

Ans: Candle flame: Light a candle and observe its flame. The bluish color at the base of the flame is where the hydrocarbon molecules vaporize and start to break apart into hydrogen and carbon atoms. Zone 3 (Dark Zone) - Pyrolysis (cracking) of the fuel begins due to the shortage of oxygen creating minute carbon particles. The zones have different colours. These are the 4 zones of a candle flame from outermost to innermost A Non luminous zone . The temperature is around 600 °C (The temperature in each zone changes among different candles and environments). It is known as luminous zone. The fourth zone of the candle (sometimes call the veil) is the faint outside blue edge that extends from the blue zone at the base of the flame and up the sides of the flame cone. The open flame is an avenue for communication to other realms of existence, making it useful for carrying prayers, transmitting chants and asking questions.
