Question
A bomb calorimeter, or constant volume calorimeter, is a device often used to determine the heat of combustion of fuels and the energy content of foods. Since the "bomb" itself can absorb energy, a separate experiment is needed to determine the heat capacity of the calorimeter. This is known as calibrating the calorimeter. In the laboratory a student burns a 0.611 g sample of para-benzoquinone (C6H4O2) in a bomb calorimeter containing 1160 g of water. The temperature increases from 25.40°C to 28.10°C. The heat capacity of water is 4.184 J/(g °C). The molar heat of combustion is -2747 kJ per mole of para-benzoquinone. C6H4O2 (s) + 602 (g) →6CO2(g) + 2H2O(l) + Energy Ignition wires Thermometer Stirrer heat sample Water Insulated Sample Burning Steel outside dish sample bomb chamber Previous Next>>/nIgnition wires heat Thermometer Stirrer sample Water Insulated Sample Burning Steel outside dish sample bomb chamber Combustion (bomb) calorimeter.
