The hottest zone of a candle flame is the non-luminous zone
• The non-luminous zone of a candle flame is the area closest to the wick, where the combustion process begins.
• This zone is where the wax vaporizes and mixes with oxygen to undergo combustion, producing heat and light.
• Despite being the hottest part of the flame, the non-luminous zone does not emit visible light, hence the term "non-luminous."
• The temperature in this zone can reach up to 1400 degrees Celsius, making it the hottest part of the flame.
• The non-luminous zone is crucial for sustaining the combustion process in a candle flame, as it provides the necessary heat to keep the reaction going.
Overall, understanding the different zones of a candle flame, including the non-luminous zone, is essential for gaining insights into the combustion process and the factors that influence the efficiency of burning.
