Candle burning
Chemical change: production of energy (light) the wick
Candle burning is a process that involves the combustion of a solid wax material with the aid of a wick. When the candle is lit, the heat from the flame melts the solid wax near the wick, causing the wax to travel up the wick by capillary action. Once the liquid wax reaches the flame, it vaporizes and reacts with the oxygen in the air to produce carbon dioxide and water vapor. This exothermic reaction releases heat, which in turn melts more wax and sustains the flame.
The color and flicker of the flame depends on the type of wax used, the wick material, and the presence of impurities in the wax. For example, candles made from beeswax typically have a brighter, cleaner flame than those made from paraffin wax, which can produce more soot and smoke.
It is important to note that burning candles can release harmful pollutants such as particulate matter and volatile organic compounds (VOCs) into the air, which can be a health concern if not properly ventilated. Additionally, proper candle care, such as trimming the wick and removing excess wax, can improve the overall burning experience and safety.
