Question

Wood burns with a flame while charcoal made from wood burns without a flame. Why does charcoal burn without a flame?​

Answer 1

Answer:

The substances which vapourise during burning, give flames. For example, kerosene oil and molten wax rise through the wick and are vapourised during burning and form flames. Charcoal, on the other hand, does not vapourise and so does not produce a flame.
