Observe a saturated solution of potassium chloride prepared at 60°C

Observe a saturated solution of potassium chloride prepared at 60°C is allowed to cool to room temperature. 

Answer: Since the solution is a saturated solution, and prepared at 60 C which is above the room temperature, therefore, while it is allowed to cool at room temperature some of the potassium chloride will settle down at the bottom, because saturation decreases with decrease in temperature.
