Why does sugar disolves in hot liquids & not as easy in cold liquids?
Answers:
simple
when liquids are heated they expand. so the intermolecular spaces increase and now they easily accomodate the sugar molecules.
hence sugar dissolves easily in hot liquids.
Cold water particles are more close together. The heated liquid is opposite, further apart, thus able to absorb the particles.
It has something to do with chemistry... but I didn't do so well in that class...
the solubility of a solution is always greater when the heat is higher. More solute will dissolve in a solvent at a higher temperature. Water can only dissolve a certain amount of solute at a certain temperature, making a saturated solution. Beyond that, the water will not dissolve any more of that particular solute. It is possible to make a super saturated solution, but that is more difficult. To make a super saturated sugar solution, you would need to heat up the water, dissolve as much sugar as will dissolve to make a saturated solution, and then let it cool, slowly and undisturbed. If you were to add any sort of contaminant, the sugar would crystallize, Which is how rock candy is made.
