Question

the passage below describes an experiment. read the passage and then follow the instructions below. mandy set 15 drinking glasses on her countertop. she poured the same amount of water into each glass, putting 40°f water into five glasses, 65°f water into five glasses, and 120°f water into five glasses. then, mandy added one teaspoon of sugar to each glass and measured the time it took the sugar to dissolve completely in the water. identify the question that mandys experiment can best answer. when sugar is added to water, does the waters temperature affect the amount of time it takes the sugar to dissolve? does one teaspoon of sugar take less time to dissolve in water than five teaspoons of sugar? does water temperature affect the total amount of sugar that can be dissolved in water?

Explanation:

Mandy's experiment has different water - temperatures and measures sugar - dissolution time with a fixed amount of sugar. So, it's about the impact of water temperature on sugar - dissolution time.

Answer:

When sugar is added to water, does the water's temperature affect the amount of time it takes the sugar to dissolve?
