Question

The substances which vapourise during burning produce a flame.

• A. True
• B. False

Answer 1

The correct option is A True

The substances that vaporize 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 vapourize and so does not produce a flame.
