Dissolving sugar in water is an example of physical change.

Answer 2

If the chemical formulas do not change, then any changes are physical changes. A good example of that is dissolving sugar in water. Once the sugar has all dissolved, you have molecules of sugar mixed in with the molecules of water. The chemical formulas at the end are the same as they were at the start, so this is a physical change.

C12H22O11 + H2O = C12H22O11 + H2O
