Potential Source of Errors:
There was a high degree of experimental error in the balance beam, due to inaccurate measurements that were conducted. A better alternative would have been the use of electronic digital scale. There was also a high degree of error in the measurement of the temperature as we could never be sure if the substance was fully burned. The temperature measurements can vary depending on the type and quality of the thermometer being used and the accuracy of the student taking the temperature.
Conclusion:
If the cheeto has the most amount of calories then, the temperature will be higher in comparison to the other chips. After testing with different chips, the experiments show that my hypothesis was not correct. In order to raise the temperature of water from 20 °C to 100 °C, 2000 calories were needed when burning the peanut with a mass of 0.5g. In an another experiment, the temperature raised from 22°C to 44°C and 1125 calories were required for the 1.2 g cheeto to burn. The mass of the chip does not affect the amount of heat needed to raise the temperature of the water. The last three experiments also proved that I was wrong. When we burned the hot cheeto weighing 1.6g it only took 325 calories to burn which is considerably lower than the amount of energy needed to burn the peanut, even though the peanut weighs less than the hot cheeto. The ranked order of my foods in decreasing calorie per gram ratio is as follows: Peanut (4000 cal/g), Cheeto (937.5 cal/g), Hot Frito (687.5 cal/g), Ruffle (229.2 cal/g), Hot Cheeto (203.1 cal/g). The mass of the chips does not affect the amount of energy (calories) needed to raise the temperature of water.
