Crystallization from a solution is which type of change?

Explanation:
Crystallization from a solution is a physical change because it changes how the particles are arranged and what phase they are in, without changing their chemical identity. When a solution becomes supersaturated, solute particles come out of solution and form a solid, ordered lattice. The substance that crystallizes is the same chemical species as before; no new substance is produced and no bonds are broken or formed to create a different compound. Energy changes can drive the process (like cooling or solvent evaporation), but the fundamental transformation is just a rearrangement from dissolved state to solid.
