Smoking a cigarette involves a combination of physical and chemical changes. The act of lighting the cigarette and burning the tobacco involves a chemical change, producing new substances. The process of inhaling and exhaling the smoke is a physical change as it involves a change in state (from solid to gas) without altering the chemical composition of the smoke.
It is a chemical change, even though the cigarette is getting physically smaller. When heat is added and you inhale the chemicals, the cigarette burns and you blow out smoke which in itself is a chemical reaction that cannot be reversed. Therefore, it's purely chemical. Remember that chemical changes cannot be reversed and physical changes can. Freezing water and then melting it is an example of a physical change. The example you mentioned is a chemical change.

The amount of nicotine in each cigarette is approximately 1 mg. This makes it a very small percentage of all of the chemicals in a cigarette. (Just the nicotine is the addictive component.)
No, being a liquid the gasoline puts out the cigarette before it can ignite. Yet if there is enough gas vapor in the air, that could possibly light before the cigarette is put out. But most often ignition requires a flame not a burning ember. Check it out on myth busters
Carbon monoxide is the chemical in cigarette smoke that reduces the ability of blood to carry oxygen. It binds to hemoglobin in red blood cells more readily than oxygen, displacing oxygen and impairing its transportation to tissues.
A well known, legal and rather dangerous chemical is hydrochloric acid.
Probably Grease or Chemical.
No.
Not nicotine yo. ------------------------ Indeed. Cigarette makers are not required to list the chemical additives in their cigarettes, but anecdotal information on the increased difficulty in quitting them v unadulterated tobacco suggests that it may not be nicotine.
Gasoline
Burning a cigarette is a chemical reaction.
The tank and the automatic rifle and grenades and larger mortar fire are the most dangerous weapons. The most dangerous chemical weapon was the mustard gas the Germans used.
It depends what chemical it is. Most likely yes.
Smoking is a chemical process.
Without the smoke, it is completely harmless. Every danger in smoking comes from the smoking aspect of it.
