Note : Wax and kerosene lamps have wicks. Molten wax and kerosene oil rise through the wick, get vaporized on burning and form flames. The substances which vapourise on burning give flames.


The type of flame depends on amount of oxygen available for burning the fuel

  • If oxygen supply is less, color of flame is yellow
  • If oxygen supply is sufficient, color of flame is blue
