Abstract A Bomb Calorimeter is used to be able to measure the heating value of a given fuel. By measuring the temperature of the water where the bomb is immersed, the difference in temperature from the time of ignition to the time of final temperature or the energy released from combustion is used to obtain the heating value of the fuel c. I. Introduction Constant Volume Calorimetry or Bomb Calorimetry is used to be able to compute the heat of combustion or heating value. Bomb Calorimetry is specifically used for measuring heating value for a combustion reaction, due to its difficulty this method is not commonly used compared to a coffee-cup calorimetry which is used to measure the heat capacity of most common fluids. Bomb Calorimetry is an adiabatic system since the set-up is contained in an insulated container, there should be no heat transfer between the calorimeter and its surroundings. When calibration is done in Bomb Calorimetry, the water equivalent or the thermal capacity of the bomb and water container is measured and calculated with the heating value of the fuel known. II. Methodology The objective of this experiment is to be able to calculate the heating value of fuel. During the experiment, first the capsule and wire must be weighed and recorded. Tape is then place on the capsule to seal it with a slit where the fuse wire can pass through, and then this must also be weighted. Fuel is then injected to the capsule and weighted, the fuel must not exceed 1 gram. After weighting the capsule, wire and fuel, these will be placed onto the cover of the bomb. The wire should be touching the fuel but should not be touching the capsule. A small amount of water is poured into the bomb and the bomb is then sealed. Pressurized oxygen is pumped into the bomb until pressure reaches 30 atm. 2000 g of water is then measured and poured into the oval pail, which is placed inside the insulated container. The electrical wiring is connected to t
