decrease. Give two reasons. 9.62. The heating value of a fuel oil is to be measured in a constant-volume bomb calorimeter. The bomb is charged with oxygen and 0.00215 lbm of the fuel and is then sealed and immersed in an insulated container of water. The initial temperature of the system is 77.00°F. The fuel-oxygen mixture is ignited, and the fuel is completely consumed. The combustion products are CO2(g) and H2O(v). The final calorimeter temperature is 89.06°F. The mass of...
