Multiple Choice

The picture shows how you might change an variable in an experiment about what affects the rate of dissolving. What results do you expect to see?

• A will dissolve slowest because it has the largest number of particles.

• D will dissolve slowest because it has the smallest surface area.

• All pieces will dissolve at an equal rate.

• C will dissolve slowest because it has the most bonds between sugar molecules.
