Yes. Temperature is not a measure of heat. In its literal sense, it is a measure of molecular motion. Hotter objects have atoms moving at greater speeds. The faster moving atoms in warm water bombard the sugar molecules with greater velocity thus making it dissolve faster than cold water, which contains slower moving atoms.
Powdered sugar will dissolve more rapidly in hot water than in cold water. The increased temperature of the water enhances the kinetic energy of the molecules, allowing the sugar particles to break apart and dissolve more quickly. In contrast, cold water molecules have less energy, leading to slower dissolution.
Even in cold water sugar will dissolve eventually, but it does dissolve faster in hot water. Hot water molecules move faster than cold water molecules and therefore can more easily break sugar molecules out of solid sugar and into solution.
Use cold water. Using hot water means you need to wait for it to cool. It also means that - because of the way solubility works - you might not add enough water. If you want the sugar to dissolve quicker, stir it.
Yes, just not as quickly
Sugar will dissolve faster in hot water than it will in cold water.
Adding sugar to cold water is the absolute slowest way to dissolve the sugar. If you're wanting to dissolve sugar at a very fast rate, add some sugar crystals in a hot beverage.
Yes, sugar can dissolve in a clear glass of cold water without stirring, but it will dissolve more slowly compared to if the water were warm. The process can be accelerated by stirring or heating the water.
They are made of pure sugar, and sugar dissolves in water.
sooner of later the sugar would break down
Hot water because the heat helps to dissolve the sugar.
Hot water. Hot water can also dissolve slightly more sugar than cold water can.
Solid oxygen. Though it might make one hell of a bang ;) Formed at -218 Celcius, or 54 Kelvin.
