What is calorimetry used to measure?
AThe mass of a product formed by a reaction
BThe heat transferred to or from a substance
CThe speed at which a chemical bond breaks
DThe volume of gas released during a change
Answer & Solution
Correct answer: B. The heat transferred to or from a substance
1. Calorimetry measures the amount of heat involved in a chemical or physical process.
2. Heat is exchanged with a calibrated object called a calorimeter.
3. The temperature change recorded by the calorimeter is used to work out the heat transferred.
4. Masses and volumes are measured by other methods, not by a calorimeter.
