Question

how can we convert saturated solution into unsaturated solution by heating

Answer 1

If the solubility of the solute in the solvent is directly proportional to the temperature, then increasing the temperature of the system will make a saturated solution - unsaturated. There may be other ways too, but I think the easiest way would be to just add more solvent.

Answer 2

Saturated solution can be converted to unsaturated solution by heating because the water molecules gets disturbed and create more space between themselves. The intermolecular force of attraction decreases and the solute molecules gets dissolved in it.
