Question

If you hold a piece of iron wire with a pair of tongs inside a candle flame or a Bunsen burner flame, what will you observe? Will it produce a flame?

Answer 1

Iron wire inside a candle flame or a Bunsen burner flame :-

• Since solid metals have a high ignition temperature and good thermal conductivity, the majority of their atoms are unable to access oxygen atoms, which prevents them from burning efficiently in normal circumstances.
• A piece of iron$\left(\mathrm{Fe}\right)$ wire will turn red-hot if we place it inside the bunsen burner's flame candle.
• As the iron gets heated enough to slightly melt, it glows a bright yellow-orange colour.
• The iron will glow and turn red, but no flame will be formed.

Therefore, if we hold a piece of iron wire inside the flame of a candle or a bunsen burner with a pair of tongs, it will turn red without producing flames.
