How will adding different flavors of kool-aid affect the boiling point of water?

Dissolving a material in water elevates the boiling point. Kool-Aid in water has a higher boiling point than water alone. The freezing point of the Kool-aid solution, however, will be lower than the freezing point of water. This chemical principle is why a 50/50 solution of antifreeze and water is used as a coolant in cars -- not only does it prevent the coolant from freezing (and cracking the engine block), it also prevents the engine from overheating.
