The drying of tobacco leaves primarily represents a physical change. During the drying process, moisture is removed from the leaves, which alters their physical state and appearance (e.g., drying makes them crisp), but it does not change the chemical structure of the compounds present in the leaves.
In a physical change, the substance remains the same at the molecular level, even though its physical properties (such as moisture content) change. In contrast, a chemical change would involve a transformation that alters the chemical composition of the substance. In the case of drying tobacco leaves, no new substances are formed, and the original chemical makeup of the leaves is largely retained.
