Why does a candle burn out?
« on: 09/11/2008 22:49:19 »
Andrerw asked the Naked Scientists:

I would like to know why a candle burns out i.e. where does the wax go?

Thanks

What do you think?

It is converted to a mixutur of gases, largely CO2 and water vapour.

To elaborate slightly, the heat of the flame melts and evaporates the wax, and then the wax vapour rises and is burned in the flame.
