During a very light activity, such as reading or watching television, the average adult expends about 7 kJ/min. If you are going to read lectures for ENCHEM 1 for 3 hours, how many Calories (kcal) do you need? What should you eat prior to reading to have this energy? Take photos of the nutritional information of the food (if available) you are going to eat and verify whether the declared Calories (Kcal) are true by doing the fuel value estimation of the food. Or if you choose food with no nutritional information label like in the case of eating apple, you can take the picture of that apple then weigh the apple and refer to the data given in the Calorimetry lecture to perform fuel value estimation expressed in Calories unit. You can choose more than 1 food and you have to provide how many servings of this food you are going to eat. Show your computation for the fuel value estimation of fod.

A sample of 7.0g of olive oil was burned in a calorimeter. The calorimeter was calibrated to have a heat capacity of 7.51 kcal/ °C. The heat released caused the temperature of the calorimeter to increase 8.3 °C. Calculate the food caloric content of the olive oil in nutritional calories per gram to three significant figures. Recall that 1 nutritional calorie (Cal) = 1 kcal.
