What is Energy Content in Food Experiment about?
The document describes how to use calorimetry to measure the energy content of foods. Key steps include heating a food sample until combustion, using the flame to heat water in a boiling tube, and measuring the temperature change of the water. The energy transferred to the water can then be calculated using the formula: energy transferred (J) = mass of water (g) × 4.2 (J/g°C) × temperature increase (°C). When 0.5g of a food raised the temperature of 10cm3 of water by 20°C, the energy content of the food was
