Why doesn't the flame on a candle touch the wick?

Answer 1

Combustion after the appliance of a flame is maintained by the wax. Without the wax, the wick would be consumed in a matter of seconds. In order to slow the progression of the flame, wax impedes the fame. To keep the flame from burning out, once the wax becomes liquid, it will boil and give off a slight composition of combustible gases. Wax is flammable. Once the candle burns down, the wax at the bottom doesn't melt as easily as the top due to the constant heating and cooling cycles. Therefore, the flame is essentially snuffed out because the wick cannot burn any further as solid wax yields to a lower temperature than the wick can maintain. The wick basically gets too short.

Answer 2

It actually does, but it won't touch the actual wax of the candle below it. Because the wick is mainly there just to provide a source for the flame. The heat of the flame melts the wax beneath it, and it continues to burn because the wax vapours give the flame a fuel source.

Answer 3

The flame on a candle doesn't touch the wick because the liquid wax at the base of the wick is drawn up by capillary action and vaporized by the heat from the flame. The flame burns the vaporized wax, creating light and heat. The wick serves as a channel to deliver the liquid wax to the flame without the flame directly touching the wick.

Answer 4

the wind pushes the flame around
