Cheetos Combustion Assignment Data Collection peck of the Cheetos, Calorimeter and measure of the Temperature and Volume of piss supply Trial Number          in advance Mass of Cheetos [g] ± 0.01g          aft(prenominal) Mass of Cheetos [g] ± 0.01g         Mass of Calorimeter [g] ± 0.01g         Volume of pissing [mL] ± 0.01mL         Temperature of pissing 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 are ever-changing from orange to black in tinct as they are burned.         The flames are coming out of the group O holes.          shutout is coming out of the oxygen holes. Data Processing and intro sub stitute 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 commove Gained By Water -let c be the specific heat capacitor of water Heat = mwater * cwater * ?T Heat = 50.00g * 4.184j/gC° * 66.0°C Heat = 13 807.20J Amount of Heat Gained By Calorimeter -let c be the specific heat capacity for aluminum Heat = mcalorimeter * ccalorimeter * ?T Heat = 27.90g * 0.897j/gC° * 66°C Heat = 1 651.
