Question

how flames are formed by a vapor wr can tell vapor spread all atound in a bix of water when we heat but why not in the candel its not​

Answer 1

Answer:

As the heat of the wax vapor flame melts more of the solid wax it creates more fuel for the flame to burn. The candle will only go out once it runs out of wax or oxygen—or gets blown out. After a candle goes out you can actually see the wax vapor escaping as a stream of white smoke.Heat from the flame travels in three directions at once by processes called conduction, convection, and radiation. Conduction carries heat down the wick to melt more wax at the top of the candlestick (it also carries down into the solid base of the candle, which gets noticeably warm to the touch).
