Cheetos Combustion Assignment Data Collection peck of the Cheetos, Calorimeter and cake of the Temperature and majority of water supply Trial crook          come in front Mass of Cheetos [g] ± 0.01g          afterward Mass of Cheetos [g] ± 0.01g         Mass of Calorimeter [g] ± 0.01g         Volume of irrigate [mL] ± 0.01mL         Temperature of Water Before thaw [°C] ± 0.1°C         Temperature of Water After raise uping [°C] ± 0.1°C 1         4.74         0.12         27.90         50.00         25.0         91.0 Qualitative Observations         Cheetos ar changing from orange to sullen in tinct as they are burned.         The flames are attack out of the group O holes.         Smoke is coming out of the oxygen holes. Data Processing and Presentation Change in Temperature Tchange = Tafter - Tbefore Tchange = 91.0°C - 25.0°C Tchange = 66.0°C Change in Mass mchange = mafter - mbefore mchange = 4.74g - 0.12g mchange = 4.62g Amount of instigate Gained By Water -let c be the specific heat capacitor of water wake up = mwater * cwater * ?T erupt = 50.00g * 4.184j/gC° * 66.0°C Heat = 13 807.20J Amount of Heat Gained By Calorimeter -let c be the specific heat cleverness for aluminum Heat = mcalorimeter * ccalorimeter * ?T Heat = 27.90g * 0.897j/gC° * 66°C Heat = 1 651.

7358J Total Heat Gained Htotal = Hcalorimeter + Hwater Htotal = 13 807.20J + 1 651.7358J Htotal = 15 458.94J Conversion From Joules to Kilojoules 16 458.94J = x kJ 16437.73J = 15.5kJ Amount of Heat Gained from 50g of Cheetos -let x be the mensuration of heat gained from 50g of Cheetos 16.5kJ/4.62g = x kJ/50g x = 167.7kJ Conclusion Conversion From Kilocalories to Kilojoules 290 kilogram calories * 4.184kilojoule/kilocalorie = 1.21*103kilojoules Percentage Error Perror = [|[actual value - divinatory value]| / suppositious value] * 100% Perror = [|[167.7kJ - 1.21*103kJ]|/ 1.21 * 103kJ] * 100% Perror =...
