Solution
This statement is True.
Correct Statement:
The substances that vaporise during burning produce flames. When a fuel is heated, it undergoes vaporization and the vapours mix with oxygen in the air to combust, producing a flame. This is why liquid fuels like petrol, kerosene and alcohol give off flames when they burn, as they vaporise before combustion.
