5. Which tablet size and the liquid combination resulted in the fastest dissolution times? A. crushed, room temperature water B. crushed, hot water © crushed, room temperature vinegar Ď. broken, hot water E. broken, room temperature vinegar 6. What is the relationship between particle size and the time it takes for the tablet to dissolve? A direct proportion B. inverse proportion C. combined proportion D. joint proportion 7. Using the activity as a model, how does mechanical weathering (breaking or crushing) contribute to chemical weathering (dissolution)? A. Increases size of particles B. Decreases dissolution time © Increases surface area D. Both A and B E. Both B and C 8. A) When a rock is physically broken down into smaller pieces, the amount of surface area exposed to weathering agents increases. Hence, chemical weathering is enhanced. B) As an effect of the chemical weathering, the rock weakens, thus becoming more susceptible to physical weathering. A. Statement A is true; Statement B is false. © Both statements are true. D. Both statements are false. B. Statement A is false; statement B is true. 9. How do we compare dissolution times in room temperature water to that of hot water?
