The Science of How a Candle Burns

  • Have you ever looked at a candle's flame and wondered the chemistry is behind that glow?
    When you light a candle’s wick the reaction begins. At the base of the wick, the flame is HOT - over 500º C. This melts the solid wax into a liquid that the absorbent wick sucks up into the flame, where the hydrocarbons get so hot they vaporize into a gas. The gaseous hydrocarbons react with oxygen in the air to form carbon dioxide and water vapor and then release the energy in the form of heat and light. This reaction is called combustion.
    Let’s try some experiments to see how this works in practice.

    one of humankinds oldest inventions, the candle is still a wonder of chemistry.

    Chemistry classes should be as practical as this. Makes it more relatable for students.

    Wow this whole time I thought the wax was meant to melt slowly so the fire lasted longer. Didn't know until now the wax is actually a fuel.

    I am not a scientist nor even a science teacher, but as an english teacher I teach science and I am I'd like to think interested and intelligent enough to understand this. I am going to use this in my class to illustrate the three basic states of matter but I need to get this straight in my head.
    The match starts the wick burning which heats the *solid* wax creating *liquid* wax which is absorbed by the wick. The heat then evaporates the wax and creates wax vapour *gas* which is finally subject to combustion in the flame producing I suppose CO2, and water vapour. What happens to the wick, does it burn as (mostly invisible) carbon smoke?

      Google would probably be better source than me but I can tell you at least that sounds right.

      If I had to guess, the wick's ignition temperature is probably lower than the vaporization point of the wax. Thus, as long as liquid wax is flowing into the wick, the heat in the wick goes to vaporizing the wax (and that wax vapor goes on to produce the candle flame)

    If the melted wax converts into gas , then why do we see drops of it travelling down the candle and collecting at the bottom?

    • @River_dawg
      @River_dawg Год назад +4

      @randomartSs Due to the heat of the flame the wax melts at a faster rate than the rate at which the wick absorbs and combusts the melted wax.

    Did anyone else think that it stayed on the Wick because the wick is dry?

    So basically the wax helps the flame keep burning without using up much of the wick thats good to know
