The dissolving of sugar in water is considered a **physical change** rather than a chemical change. Here are the reasons why:
1. **Reversibility**: When sugar dissolves in water, it can be recovered by evaporating the water. This shows that the process is reversible, which is a characteristic of physical changes.
2. **Chemical Structure**: The molecular structure of sugar (sucrose) does not change when it dissolves in water. The sugar molecules remain intact; they simply become surrounded by water molecules. No new substances are formed.
3. **No Chemical Reaction**: In a chemical change, new substances are produced as a result of a chemical reaction. In the case of dissolving sugar, no such reaction occurs; the sugar simply disperses in the water.
In summary, since the process of sugar dissolving in water does not result in a change of its chemical composition and can be reversed, it is categorized as a physical change.
