Title: to investigate how much energy (Kj) is stored in different types of peanuts and how much is released. Planning Background information: - The most common way to measure energy in a substance is to burn it. By using a relevant method and a formula, you can find out the amount of energy there is in peanuts. Heat produced by combustion of food (E) = m??t for the water in test tube. E represents energy, m is the mass of water which is determined from the volume. ? (theta) is the specified heat capacity of water, this is a standard value = 4.19J/g/°C, ?t stands for the change in the temperature of the water. So the amount of energy (E) in the heat gained by the water is given by the product of m×c×T. From my research, I found out that food factories use a bomb calorimeter which is very accurate and...
