Does sugar melt faster in hot or cold water?
On One Hand: Hot Water Dissolves Sugar QuicklySugar dissolves quickly in hot water because the water temperature creates faster molecular movement of the sugar molecules. Faster molecular movement yields faster reactions with the surrounding molecules, ultimately breaking up the sugar. Consider that sugar in hot tea does not need to be stirred to dissolve.On the Other: Cold Water Dissolves Sugar SlowlyMolecules move more slowly as the surrounding temperature gets cooler. Sugar molecules in cold water move more slowly. Note that sugar poured into iced tea must be mixed to dissolve.Bottom LineMolecules move more slowly as the surrounding temperature gets cooler.
