Ignition wires heat Thermometer Stirrer A bomb calorimeter, or a constant volume calorimeter, is a device often used to determine the heat of combustion of fuels and the energy content of foods. sample In an experiment, a 0.8006 g sample of phthalic acid (C3H,04) is burned completely in a bomb calorimeter. The calorimeter is surrounded by 1.112×10° g of water. During the combustion the temperature increases from 23.08 to 25.98 °C. The heat capacity of water is 4.184 J gl°C•! Water The heat capacity of the calorimeter was determined in a previous experiment to be 891.8 J/°C. Assuming that no energy is lost to the surroundings, calculate the molar heat of combustion of phthalic acid based on these data. C3H,O4(s) – (15/2) O2(g) →3 H2O(1) = 8 CO>(g) + Energy Insulated outside chamber Sample dish Burning sample Steel bomb Molar Heat of Combustion = kJ/mol Combustion (bomb) calorimeter.
