Burning iron
Would you have
thought that even iron could be made toburn with a flame! Twist some fine steel
wool round a small piece of wood and hold it in a candle flame. The metal
begins to blaze and scatter sparks like a sparkler. The oxidation, which was
slow in the previous experiment, is rapid in this case. The iron combines with
the oxygen in the air to form iron oxide. The temperature thus produced is
higher than the melting point of iron. Because of the falling red-hot particles
of iron it is advisable to carry out the experiment in a basin.
