what is different between the gas of the in the inner part of the burning candle and the outer part of the burning candle
Answers
Inner Part: This is the innermost part of the flame. It is the part closest to the wick. You might assume that this is the hottest part of the flame. However, it is the least hot. This is the black part of the flames that contains unburnt particles of the carbon from the wick i.e. unburnt fuel.
Middle Part: This is the biggest part of the flame. The colors in this are varying shades of yellow and orange. This is the luminous flame because it emits light. This part is also not extremely hot. This is because this part gets a limited supply of oxygen. So incomplete combustion takes place here. Which is why it burns orange and is luminous.
Outer Part: Now this is the hottest part of the flame. This part has an unlimited supply of oxygen. So complete combustion takes place here. Hence it is the hottest part of the flame. Also, this part of the flames burns with a blue color. It is the non-luminous, i.e. does not emit light
