13. While completing your calorimetry report and snacking on some peanuts, your mind begins to wander... calorimetry must have something to do with calories, the words are so similar, and your recent inactivity has you concerned about the number of calories in these peanuts... You have heard of a technique called bomb calorimetry, which burns a sample in oxygen in a sealed container (the bomb) surrounded by water in a calorimeter. The temperature change of the water is measured and used to determine the energy released by burning the sample. Perhaps you could do something similar with a peanut.' Measuring 125mL of water into a soda can, you hang it over your peanut, which you have mounted on a coiled paper clip. You ignite the peanut, let it burn completely and monitor the change in temperature of the water. As the peanut burns, the water temperature increases from 20.0C to 59.0C. Specific heat of water =4.184J/g1deg1,1mL water =1g water a) Calculate the energy in J stored in your peanut? b) How are joules, calories (with a lower-case c) and Calories (with a capital C) related? c) Show how to convert your answer from a) to calories, and to food Calories d) If the average peanut has 6 Calories, how many peanuts would you need to burn to bring the water in the can to a boil? e) Compare your Calorie value from c) to the theoretical average value in d), what is the % error in your answer? f) Identify two likely causes of the observed deviation from the theoretical value
