Worked Solution & Example Answer:Calorimeter 1 and Calorimeter 2 were each electrically calibrated - VCE - SSCE Chemistry - Question 26 - 2022 - Paper 1
Step 1
Which one of the following statements is correct?
Answer
To determine which statement is correct, we need to analyze the information provided. Since Calorimeter 2 has better insulation than Calorimeter 1, it would result in less heat loss to the surroundings during the reaction, which means a more accurate measurement of the temperature change.
Considering the options:
- A: This statement implies that Calorimeter 1 is the only one suitable for calculating ; however, both calorimeters can measure based on the temperature changes recorded.
- B: This is a reasonable statement, as less heat loss in Calorimeter 2 due to better insulation would suggest it’s more efficient in measuring the reaction's thermal changes.
- C: This statement regarding calibration factors is not necessarily supported by the given graphs. Therefore, it cannot be confirmed.
- D: This statement can't be definitively established from the details provided, and without clear data indicating the temperature increase, it remains ambiguous.
Based on these assessments, the correct statement is B: Calorimeter 2 has better insulation than Calorimeter 1.
