Question: 102
12. Which of the following devices would be the most appropriate to use to measure the heat capacity of a liquid?
- A. Thermometer
- B. Calorimeter
- C. Barometer
- D. Volumetric flask
Correct Answer: B
Explanation:
A calorimeter measures heat transfer. Although calorimeters often incorporate thermometers, the thermometer itself only tracks temperature, not the heat transfer itself, so choice (A) is incorrect. Choice (C) is irrelevant; barometers measure changes in pressure. Choice (D) is also incorrect because volumetric flasks measure quantities of liquid, not the heat capacity of the liquid.
