Candles
The wax that is on the wick vaporizes from the heat of the flame. Once in the gaseous state, it combines with the oxygen of the atmosphere to form the flame. This flame produces sufficient heat to keep the candle burning through the following chain of events: the heat of the flame melts the upper part of the fuel mass, which rises along the wick by capillarity, and finally the liquefied fuel is vaporized and burns inside. of the flame.
