Lab Report Essay

The experimented value was drastically different from the accepted value, which caused the percent of error to be extraordinarily high. The experimental marshmallow’s energy per gram was .073 Cal/g while the accepted marshmallow’s energy per gram was 3.33 Cal/g. The percent error for the marshmallow was 97.8%. The experimental CHEEZ-IT’s energy per gram was .531 Cal/g while the accepted CHEEZ-IT’s energy per gram was 5 Cal/g. The CHEEZ-IT’S percent error was 90%. The experimental Cheetos’ energy per gram was 1.08 Cal/g where the accepted Cheetos’ energy per gram was 5.36 Cal/g. The percent error for the Cheetos’ was 79.9%. The experimental Chex-Mix’s energy per gram was 1.52 Cal/g where the accepted Chex-Mix’s energy per gram was 4 Cal/g. The Chex-Mix’s percent error was 60%. The conclusion that was made was that through out the entire experiment there was a tremendous amount of error made due to the fact that the percent error was incredibly high.
An inference that was made was the Chex-Mix and the CHEEZ-IT burned the fastest, while the Marshmallow and Cheetos burned a tad bit slower. Another …show more content…
The underlining purpose of the experiment was to show that error is ok as long as you know what the flaws are and be able to explain they happened. The lab involved burning a Marshmallow, a CHEEZ-IT, a Cheeto, and A Chex. The heat from the burning snack food is then carried into the H2O and used to calculate the energy content. An improvement that could be made was a replacement for the paperclip; it was difficult to balance the paperclip and sample combination, a skewer connected to the table would be a better option. Another improvement could placing the sample inside a Coke Can that is cut in half with holes punctured-to keep the oxygen flow-then place the original Coke Can calorimeter on top of that to help trap in more of the heat producing a more accurate
