Answers
Answer:
1. An ideal fuel is cheap. An ideal fuel burns easily in the air at a moderate rate. It releases a large amount of energy. It should not leave behind any undesirable substances which can be harmful to us.
3. The second zone is called the Middle zone; The third zone is called as Inner zone; Due to complete combustion, the outer zone is blue

When we breathe in these particles, they end up in both our upper and lower airways, which can wreak havoc in all sorts of ways.
