Answer:
warming up the solution.
Explanation:
- A saturated solution is a chemical solution containing the maximum concentration of a solute dissolved in the solvent. The additional solute will not dissolve in a saturated solution.
- Supersaturated solution is a solution that contains more of the dissolved material than could be dissolved by the solvent under normal circumstances.
- A saturated solution can become supersaturated when it is cooled.
- Also, we can form a saturated solution from a supersaturated solution via warming up the solution:
<em>The solubility of solid solutes in liquid solvents increases as the solvent is warmed up.</em>

Answer:
Chemical change
Explanation:
Chemical changes occur through chemical reactions. In a chemical reactions, reactants combines together and gives new products. Chemical change is a kind of change in which new products are formed as a result of different bond combinations. They are often associated with the evolution and use of energy.
Chemical changes are not easily reversible and they require a considerable amount of energy. Examples of chemical changes are combustion, rusting of iron, precipitation e.t.c.
