2.32: Describe an Experiment to Investigate the Energy Content in a Food Sample

INVESTIGATING ENERGY CONTENT IN FOOD SAMPLE

Food in Complete Combustion to Heat Water

METHOD: Measure Volume of Water and Add into Boiling Tube Measure Temperature of Water Measure Mass of Food Sample Set Food Sample Alight for Complete Combustion and Put Underneath the Boiling Tube to Heat the Water until it Burns Out Measure Final Temperature of Water

EQUATION: The Equation to Calculate the Energy Transferred to the Water is: Energy transferred (J) = ( Mass of Water (g) × 4.2 × Temperature Increase (°C) )                                                                     Mass of Food (g)
