The overall goal of the experiment that we are conducting today is to find the caloric data of
different food items by recording the initial and final mass along with the initial and final
temperature. The procedure for the project given to use was to fill our can up to 100 mL, find the
temperature of the water and record the mass for both initial and final. When we find the caloric
data, we determine the ranking of each food item provided to use.
Equations used: qwater = mwaterCs,waterΔTwater
qwater = -qfood
densitywater = 1.00 g/mL
Cs,water = 1.00 cal/goC
1000 cal = 1 kcal = 1 Cal
(Qwater / 1000) * (Final mass - Initial mass)
Conclusion: The data that was found did not match the given values. The SOP had a big part in
these values.
Highest-Lowest:
1. Crouton
2. Cheese Puff
3. Corn Chip
4. Sunflower
Claim: Our estimated cal/gram for the crouton was 0.851 but the actual found was 4.29. The
estimated cal/gram for the sunflower was 0.185 but the actual was 6.00. The estimated cal/gram
for corn chip was 0.301 but the actual was 5.71. This shows that the SOP played a huge part in
the number difference from the estimated and the actual
