- A. Insulate the calorimeter.
- B. Use a larger volume of reactants.
- C. Conduct the experiment in an open environment.
- D. Use a metal calorimeter.
Answer
Insulate the calorimeter.
Explanation
The correct option is Insulate the calorimeter.. Insulate the calorimeter. is the best answer because it directly supports the AQA A-Level Chemistry objective to explain practical limitations and heat loss in calorimetry. This reasoning is anchored to Calorimetry and enthalpy measurements in Energetics, and it separates calorimetry from similar A-Level ideas rather than relying on a vague recall statement. Other options are weaker if they use the wrong evidence, calculation, mechanism, observation, unit, or conclusion for this subtopic.
Common mistake
Heat Loss in Calorimetry
Students often forget to account for heat loss to the surroundings when measuring temperature changes in calorimetry experiments.
To address this, always consider that some heat may escape, leading to inaccurate measurements. Use insulated containers to minimize heat loss and ensure that your calculations reflect the potential heat loss by adjusting your results accordingly.
