Experiment 8 Question 1 Estimating The Calorie Content Of Nuts 5 Points When Calorimetry Is Done For A Large Numb 1 (68.03 KiB) Viewed 59 times
Experiment #8: Question #1 - Estimating the Calorie Content of Nuts (5 points) When calorimetry is done for a large number of foods, we can decide which foods eat and which to avoid to manage our weight. The goal of this experiment was to determine the caloric content (Calories per gram) for a Planter's peanut. It is clear that calorimetry works on the basis of transferring the heat released by the food stu to a water reservoir. We calculate that energy (9soln = msoln X S.H.soln XATsoln ) from a knowledge of: (1) the change in temperature of the water - ATsoln (2) the mass of the water that was heated -msoln (3) a knowledge how well water stores heat - called the specific heat constant - S.H.soln BE EEEEE
Question Completion Status: 5 6 8 7 3 9 10 However, there is an experimental flaw (oversight) in the calculation owing to something that we forgot about What other piece of information is needed in order to correctly determine the calories released by any particular food. =============== D the amount of heat that escapes from the calorimeter during the course of the experiment (lost heat) the dimensions of the water reservoir (meaning the container) O the material that the calorimeter is made from Da the amount of heat that is absorbed by the room temperature walls of the calorimeter during the course of the experiment (lost heat) De the size of the water reservoir (meaning the container)
