Is smoking a cigarette a physical or chemical change?
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.
Is smoking a cigerrette a physical change?
It is a chemical change, even though the cigarette is getting physically smaller.

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.
