Melting of ice is a physical change because it involves a change of state from solid water (ice) to liquid water. The chemical composition of the substance remains H₂O throughout the process; only its physical form changes. Physical changes are typically reversible.
A physical change alters the form or appearance of a substance but not its chemical composition.
