Question

Example. A Student wants to increase the maximum if sugar that can dissolve in water..She crushes the sugar and then stirs it into the water .Does This work?

Answer 1

Answer:

Yes this works.

Explanation:

This works because when the sugar is crushed, more of the surface area of the sugar gets exposed to the solvent, allowing the solvent to dissolve it a lot quicker than when it wasn't crushed.

Stirring also helps the sugar particles dissolve faster. This is because the particles are now agitated, which increases their kinetic energy.  This increase in Kinetic energy is reflected by increase in temperature, which helps the particles dissolve faster.

Answer 2

Answer: yes it does work.

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.
