Yes, the transformation from H₂O(s) to H₂O(l) represents a physical change. In this process, solid water (ice) is converted to liquid water. This change involves the absorption of energy (in the form of heat), which leads to the breaking of some hydrogen bonds between water molecules, allowing them to move more freely in the liquid state.
Since the chemical composition of water remains the same (H₂O) before and after the change, this is classified as a physical change rather than a chemical change.
