The correct answer is A) Crush the sugar cube into smaller pieces
Step-by-step explanation:
The dissolution rate is related to the speed something dissolves or how long it takes for a solvent, for example, water to dissolve a solute, for example, sugar. This rate is affected by multiple factors such as temperature, particle size, and proportion of the solute vs. solvent. In terms of particle size, the dissolution increase if particles are small. This implies, in the case of sugar a sugar cube dissolves slower than sugar is smaller pieces. Thus, one way to increase the dissolution rate of a sugar cube is "Crush the sugar cube into smaller pieces".
