When the students who built the Calorimeter in Figure 1 compared their calculations to the industrial Caloric values printed on food labels they noticed some differences. Study the data in the table below and answer questions 1 and 2.
1. Explain two possible reasons for the differences between the lab values and the industrial values.
2. How could the students change the Calorimeter’s design to improve the accuracy of the results?
