Exercise 1: Determination of Caloric Content of Three Foods
Data Table 1. Determining the Mass of the Water (g).
Compare the calorimeter that you built to a bomb calorimeter. How are they similar? How are
they different?
Based on your results, was this setup a good way to measure Calories as opposed to a bomb
calorimeter? What types of experimental error may have occurred with this experiment? How
might you design this setup differently if you had unlimited expenses for materials?
Based on how each food burned, which food would be the best to use for a fuel that has a steady
flame and might burn for a long time? What was the composition of this food (which
macromolecule was it mostly composed of)? How does this relate to the way that the human
body utilizes this type of macromolecule as fuel?
Although protein was part of the composition of the foods in this experiment, it was not the main
macromolecule component of the nut or the marshmallow. Why do you think this type of food
may have been left out, based on what you learned about the way the fuel is “burned” in the
body?
