Water temperature affects the rate at which sugar dissolves. Sugar dissolves faster in warmer water than it does in cooler water. Two things are required for a substance to dissolve and create a solution: the substance itself, or the solute, and the substance it is dissolving into, or the solvent.


The color and sugar in the room-temperature water dissolve somewhere between the cold and hot water, but are more similar to the cold than the hot. Note: There are actually two processes happening in this activity. The color and sugar are dissolving in the water but they are also diffusing in the water.




If you add a sugar cube to a cup of room-temperature water and another sugar cube to a cup of hot water, you'll find that the sugar dissolves faster in the cup of hot water. The sugar particles move around and interact more at higher temperatures because the additional heat adds more energy to the process.


Videos and illustrations from Chapter 5, Lesson 6 of the Middle School Chemistry Unit produced by the American Chemical Society. ... Why Does Water Dissolve Sugar? ...

Stir continuously until the sugar is dissolved. Stirring at the beginning of the process helps break up lumps and make sure that the sugar is heated evenly. It's best to use a wooden spoon. Keep stirring until the sugar mixture turns clear and begins to boil. At this step, different candies can be made based on the final temperature of the sugar.


Has anyone experienced a difference in quality of wine because of high temperature sugar solution added to wine or must? Dissolved sugar into a simple syrup/solution for sweeteing or backsweetening, does anyone have an opinion on whether or not very high temperatures will have an effect on the cooler wine solution it is added to?




1. Prepare the area by sitting down the paper towels. 2. Measure 2/3 of a cup of water and place it in a clear plastic cup 3. Set the thermometer in the water and record the temperature. 4. Place one sugar cube in the water gently, as not to spill any water. 5. Start the timer.


How to Dissolve Sugar. Food science fact #1: Water molecules are stronger than sugar molecules and have the power to break them down. This means that sugar will dissolve in any temperature water eventually. But in the kitchen where time is often of the essence, use warm or hot water to dissolve sugar quickly. ...
