Practice Question
A scientist studying solubility increased the temperature of a constant volume of water and measured the amount of sugar that dissolved into solution... Which of the following describes the relationship between the independent and dependent variables?
Answer Choices
- A: As the amount of dissolved sugar increased, the temperature of the water decreased.
- B: As the water temperature increased, the amount of dissolved sugar increased.
- C: As the amount of dissolved sugar increased, the amount of water remained constant.
- D: As the water temperature increased, the amount of water decreased.
Correct Answer: B
Rationale: Solubility of solids like sugar typically increases with temperature, so as the independent variable (water temperature) increases, the dependent variable (amount of dissolved sugar) increases.
