Why is it that, if sugar water freezes at lower temp than pure water, if you add enough sugar to water, it solidifies at room temperature (as in hard candy)?

Pure, or ionised, water freezes at 0 centigrade, and boils at 100 centigrade. In other words these are the temperatures at which the water can change state. The warmer the liquid, the more excited it's particles, so you can add more of another chemical to create a saturated solution. In other words the water will dissolve more of another chemical if it is hotter. When it returns to room temperature, in the case of sugar, the saturated solution is over-saturated and some of the sugar returns to its native state (a solid at room temperature. Thw ay that its crystaline structure works means that you see the entire solution as solid. Checking on an atomic level would reveal that this is not actually the case. Another question to ask might be to find out why nitrogen solidifies and then becomes a liquid again near absolute zero. That is spooky.
