Correct answers: hydration and increase of the surface area of the solute.
Why:
- Hydration (solvation) occurs: water molecules surround and hydrogen-bond to individual sugar molecules, pulling them into solution.
- Increasing the surface area of the solute (e.g., crushing a sugar cube) speeds the dissolving because more solute is exposed to the solvent.
Dissociation and ionization do not apply because sugar (a covalent molecule like sucrose) dissolves as intact molecules; it does not break into ions or ionize in water.
