Question

The substances which vapourise during __________, give flame.

Answer 1

1. Kerosene oil combustion results in a flame. On the other hand, other substances, like as coal, do not evaporate and as a result do not ignite.
2. Kerosene, unlike gasoline, doesn't burn quickly. Petrol has a lower auto-ignition temperature than kerosene.
3. Petrol has a lower vapour pressure than kerosene.
4. Combustion is a type of chemical process that leads to fire.
5. Flames are created at a certain stage of the combustion process known as the ignition point.
6. Carbon dioxide, water vapour, oxygen, and nitrogen make up the majority of a flame.

Flames are produced by the chemicals that vapourize during combustion.
