In this technique, a process is carried out in solution in a … Calorimetry Lab: Determining the Calories in Cheetos Introduction: Measuring the Energy in Food We get the energy we need by eating food. The energy comes from the chemical energy stored in the food that gets released during digestion. This energy is described on food labels with the unit Calorie (always with a capital C). A calorie is the amount of heat (energy) required to increase the temperature of 1 gram of water by 1 °. C. This process is the basis of the technique of calorimetry. In this lab investigation, you will use the methods of calorimetry to approximate the amount of energy contained in a potato chip and/ or other food items. Part A.1. The 200-mm test tube also contained some water (besides the metal) that was subsequently added to the calorimeter (in Part A.4). Considering a higher specific heat for water, will the temperature change in the calorimeter be higher, lower, or unaffected by this technique error? Explain.
