How can we convert the saturated solution into unsaturated by heating?

A saturated solution is said to be saturated at a given temperature when there is no more scope of solute particles to dissolve into water. This is because the solute particle has taken all the intermolecular space present in the solvent.

On heating, the molecules of solvent gain kinetic energy, start vibrating and try to move away from each other thereby accommodating some more solute particles in this space. Hence, it becomes an unsaturated solution.
