Answer: yes it does work.
Step-by-step explanation:
When the sugar is crushed by the student, an increase in the number of molecules of sugar occurs. Meaning that more number of the solute (sugar molecules) are able to interact with the solvent (the water).
Therefore, there will be more number of collisions taking place between the solute and solvent molecules.
Hence, we can say it works because this leads to more interaction or collisions between the solute and solvent particles, as a result of this increased interaction between solute and the solvent, sugar will dissolve readily into the water.
