The sublimation of air freshener

Description

Sublimation is an interesting physical change. When a substance sublimes, it changes directly from a solid to a gas without passing through the liquid state. Dry ice sublimes, as do iodine and mothballs. This experiment involves the study of another common substance that sublimes – air freshener.
