It is noted that sugar can not be used fo this experiment b/c sugar does not dissolve well in cold water. What does increasing the temperatures do to the solubility of a solute?
Is this an endothermic or exothermic change and why?
We were makeing ice cream in this experiment

When dissolving solids in a solvent as temp. increases solubility increases. When dissolving gases it is the exact opposite.

Increasing the temperatures increases the solubility. It's an endothermic change because you must add heat to complete the process. The opposite of this would be allowing a solution to cool (releasing heat in an exothermic change) and causing the solute to precipitate out.
It's been a while since I had chemistry. Hope this helps.
