Dissolving Sugar Cubes

Question:Will sugar dissolve faster in hot or cold water

Hypothesis:Hot water with sugar dissolves faster

Method:

1. Make sure the glasses have an equal amount of water

2.Put a sugar cube into the cold water and stir with a spoon until the sugar disappears.Repeat this process until the sugar stops dissolving, you are at this point when sugar starts to gather on the bottom of the glass rather than dissolving.

3.Write down how many sugar cubes you could dissolve in the cold water

4.Repeat the same process for the hot water, compare the number of sugar cubes dissolved in each liquid, which dissolved more

Result:Hot water dissolved the sugar cube faster

Conclusion:The hot water cup has faster moving molecules than the cold water cup so the hot water cup dissolves the sugar cubes faster
