Once the determination is complete, typically within 4 minutes ( depending on which model you have), the calorimeter calculates the Calorific Value ( CV ) of the fuel sample. The amount of heat evolved when one mole of a substance is burned completely in oxygen is known as the heat of combustion (or enthalpy change of combustion). g of water, a temperature rise of 3. With this apparatus a test specimen of specified mass is burned under standardised conditions. The bomb calorimeter is a closed system that can exchange energy with the surroundings and is isochloric (no volume change). After the experiment the bomb is connected to the discharging apparatus and, from this point on, the procedure varies with the particular reaction. " The sample is placed in a small metal container and lit, or combusted, so it burns up. To measure the calories of food samples by Bomb Calorimetry. A clamp may be used to support the thermometer. Once a slow, linear temperature change was observed, the room was cleared of people, and the calorimeter was ignited for five seconds. The bomb calorimeter is a laboratory device that contains a "bomb," or combustion chamber — usually constructed of non-reactive stainless steel — in which an organic compound is consumed by burning in oxygen. 187 g of benzene, C6H6, is burned in a bomb calorimeter, the surrounding water bath rises in temperature by 7.
