Answer:
Rusting of iron is corrosion and it’s a chemical change because rust is a chemical compound called hydrated iron oxide Fe2O3. nH2O, iron(III) which is different from elemental iron.
Physical changes are those changes in which substance identity is not changed and it can get back to its original form ex: water freezing to ice can be melted back to water. Whereas chemical changes are those in which original substance identity is changed and they cannot be restored to their original form.

On adding solid solutes to the solvent, some solute dissolves and its concentration increases in solution. This process is known as dissolution.
Crystallization is a process in which Solute particles in solution collide with the solid solute particles to get separated out of solution.
