The Flame of a Candle

The flame of a candle is a visible result of combustion, where wax vaporizes and reacts with oxygen in the air. When you light a wick, heat melts the surrounding wax, producing vapor that rises into the flame. Inside, these vapors mix with oxygen and ignite, creating a steady, luminous combustion process. The flame sustains itself by drawing up more wax vapor, while some carbon particles burn partially, producing the characteristic yellow glow. The flame also releases light and heat, making candles both practical and aesthetic sources of illumination.
