Answer:
1 —Powdered; 2 — Granulated; 3 — Sugar in the Raw
Explanation:
None of the beakers will dissolve. They are made of glass. However, the sugars in them will dissolve.
One of the ways to increase the rate of dissolving is to decrease the size of the solute particles, because that increases their total surface area and exposes more of the solute to the action of the solvent.
The relative sizes of the crystals and their surface areas are approximately
We see that powdered sugar has the greatest surface area so, if all other factors are the same, the order of dissolving should be
1 —Powdered; 2 — Granulated; 3 — Sugar in the Raw
