Hypothesis: The sugar will dissolve faster than the sugar cubes in all of the tests. Both materials will dissolve faster in hotter water.

What factors can you infer sped up the dissolving rate of the solute? The factors that sped up the dissolving rate of the solute include stirring, heat of water and amount or size of solute. Stirring sped up the dissolving rate because it helped break down the solute into smaller pieces that dissolve faster. The heat of water sped up the dissolving rate because since hot water moves faster than colder water, the sugar would dissolve faster. The size of the solute, the sugar or sugar cubes, effects the melting rate because the larger the volume the longer it takes to break down or dissolve.

Infer which would actually dissolve faster, a whole sugar cube or lose sugar in ice cold water? The loose sugar would dissolve faster because the cube sugar starts more compacted so it would take longer to break down while the loose sugar is already more separate, so it would break down faster. Another reason is that because more surface area as a whole is exposed in the loose sugar, it would be effected more and break down faster.
