Being a Criminal is Not Something You Are Born With, It is Something You Turn into Gradually over Ti - The bomb calorimeter is a device that burns a fuel sample and transfers the heat into a known mass of water, allowing a precise way to calculate the heating value from the weight of the fuel used and the change in the temperature of the water. This experiment also demonstrates the First Law of Thermodynamics for control mass. the combustion reaction, which eliminated the uncertainties associated with the final combustion process (Silva). Bomb calorimetry is a massive topic and a very significant addition to thermodynamic studies. Experimental Procedure: Calibration Made a benzoic acid pellet and weighed it with the goal of being close to 1 gram in mass. A 10 cm nichrome ignition wire was cut and fused to the pellet.
