Candle Wax flame is yellow and white but Gas flame is blue how?
the candle flame is yellow and white but the natural gas flame is blue how is that possible
-What is the main difference you see between the kitchen stove flame and the candle flame?
Right. The color. The stove flame burns natural gas as a blue color, while the candle flame is yellow and white.
-Why is a candle flame yellow and white, while a natural gas flame is blue?
To answer that, we need to understand what fire is. What is fire? Fire is heat and light.
The heat and light are two forms of energy that are released when certain chemicals suddenly combine with oxygen.
In the case of natural gas and candle wax, the chemicals are carbon and hydrogen chemically connected to each other.
When natural gas burns, there is plenty of oxygen around and all the carbon and hydrogen are able to completely combine
with oxygen to form a nice blue flame, which is very hot. When a candle burns, the only place where there is enough oxygen is at the bottom of the flame.
-The blue part of the flame at the bottom?
In the rest of the candle flame, there isn’t enough oxygen to combine with all the carbon and hydrogen.
Whatever carbon and hydrogen are left over form soot. When soot is heated, it glows yellow, and if the flame is hot enough, it turns white hot.
