A change of state from one from to another is known as a physical change.

When iron filing is added to copper sulphate solution, it displaces copper from its solution and the colour of the solution changes from blue to green. 

Displacement reactions are reactions in which more reactive metal takes the place of less reactive metal. 

AB + C → AC + B is a displacement reaction.
