Asolution which is heated so that it can dissolve more solute than at room temperature, then cooled down again, is referred to as

Explanation:

When a solution contains maximum concentration of solute particles into the solvent then this type of solution is known as saturated solution.

On the other hand, a solution in which presence of solute particles is very low as compared to its equilibrium solubility is known as unsaturated solution.

For example, a teaspoon full of sugar dissolves easily in a glass of water. Hence, it is an unsaturated solution.

Therefore, we can conclude that a solution which is heated so that it can dissolve more solute than at room temperature, then cooled down again, is referred to as saturated solution.
