copper wire vaporization with a candle ? Answered
This morning, I was wondering what was the maximum temperature of the flame of a simple candle.
So, this evening, despite the answer is on the internet, I made some quick and various experimentations of my own, mainly because there was nothing interesting at TV ...
I put a wire of tin with a diameter of 1 millimetre over the flame and it liquefied immediately. So I immediately deduced the temperature of the flame was over 505oK ...
Then, I tried with a wire of iron with a diameter of 1 millimetre, and it did not liquefied. So, I deduced the maximum temperature of the candle's flame was below 1811oK.
Then, I tried with a very thin wire of enameled copper (thiner than a hair), the enamel vaporized in a flash and the copper wire quickly liquefied. I deduced the max temp of the flame was over 1357oK.
This gave me a maximal temperature somewhere between 1357oK and 1811oK.
Then, I tried with a thin wire of copper (0.2 millimitres), and it liquefied. But I also noticed that, sometimes, there was a green flame adding to the candle's flame.
On the internet, they say that coppers flame are green.
This would mean that my candle's flame is hot enough to vaporize my copper wire ? and, thus, that the maximal temperature of the candle flame is over 2835oK ?????
If so, why can't it liquefy my 1 millimeters iron wire ?
