Dissolution is a physical change. Dissociation is a chemical change, usually reversible, however. The salts, for example, usually dissociate in aqueous solution, but the sugar will simply dissolve, with no ionic dissociation.

Answer:
DISSOLVING SUGAR IN WATER IS A REVERSIBLE CHANGE
- Reversible process implies that the conversion to another state of the substance can be carried to the initial state.
- Physical change implies that the product's chemical properties do not shift.
- When we dissolve the sugar in water, it dissolves entirely in water and change the taste of the water but the water's chemical properties of water and sugar do not change and by certain physical techniques the sugar can be distinguished from the water.
- Therefore, dissolution of sugar is a physical change.
