Combustion of a Candle


 
 
Concept Explanation
 

Combustion of A Candle

If we observe a candle flame closely, we will notice the following:-

  • The wick burns and it stands in a pool of liquid wax.
  • There is a small portion of unburnt wick between the flame and the liquid wax.
  • The liquid wax is trapped in a cup of solid wax.
  • The liquid or solid wax never catches fire.
  • Conclusion:

    1. It is only the wax vapours that burn. Neither liquid wax nor solid wax burns.

    2. When a candle wick is lit, the heat produced from the flame melts the wax.

    3. The wick soaks or absorbs the molten wax.
