Unsaturated, saturated, and supersaturated?

unsaturated means that the liquid can hold more of the thing that is being dissolved, saturated means it's full, but not overfull, supersaturated is when there is so much that it can't all dissolve, so there's some left over. Hotter liquids hold more, so if you heated a saturated, it would hold more, and if you cooled a saturated, it would become supersaturated.
