Dissolving is generally considered a physical change when the solute can be recovered by physical means like evaporation (e.g., salt in water). However, if the solute reacts chemically with the solvent (e.g., a metal dissolving in acid), it becomes a chemical change.
A change in the form or state of matter that does not involve a change in its chemical composition or identity.

Mnemonic
Think 'PHYSICAL' = 'PHYSICAL FORM'. If only the FORM changes (like ice to water), it's a physical change. The 'PHYSICS' of it changes, not the chemistry.
Conceptual Metaphor
CHANGE IS A JOURNEY (for a substance through different states). IDENTITY IS A CORE (the core identity remains untouched by a physical change).
