FIRE PR

Just catching up on some old threads.

Thanks to Chris for the previous text, just for tickling my sense of humour.  Just what I needed to lighten the day !

On the thread, glad I'm not having to sit an eleven plus exam, let alone an IFE exam !!

Personally I think they are all wrong!  I think when you blow (O2) out a candle you blow the flame (fire) which then loses contact with the wick & wax (fuel)..how bout dem apples!  Break in inhibited chain reaction.

thats what I said

its the vapours that burn.

Therefore if you dilute the vapours with a mixture of CO2 and oxygen you extinguish the fire because you have taken the pyrolitic reaction outside its limits of flamability.  too much o2 and it too rich to burn and too little and its starved.....so it could be either!!  

Oh the wisdom of Children.......too much for me!!
