GENG220 Engineering Thermodynamics Question: A Laboratory Exercise on Heat of Combustion. After we finished the lab we need to : Do “Discussions and Conclusions” section. Two paragraphs are enough. discuss the lab,results. accuracy,what we learned etc. Answer: Introduction: This is an experiment carried out to measure the enthalpy change whenever a substance is burned. In order to measure the capacity of heat of the bomb calorimeter, a weighted mass of a standard compound is first burned. This must be a substance with a known enthalpy of combustion. The most commonly used substance for calibration is the Benzoic acid (C6 H5 CO2 H) since it is a crystalline that can be acquired in high purity. Benzoic acid was the reference material for this experiment. Its combustion in a bomb calorimeter releases 26.38 kJ of heat per gram (Washburn, 2011). During the process of calibration, a known amount of heat is introduced to the calorimeter through the combustion of benzoic acid. This process releases energy that is equivalent to the calorimeter for a specific rise in temperature. When in need of testing an unknown sample, the heat capacity of the bomb calorimeter has to be known. The sample is the burned, the energy released is then absorbed within the calorimeter and the resultant change in temperature is taken. The data from the test results for each runs is recorded. There is need to find an accurate value that will represent the overall change in temperature that resulted from the burning reaction. The data can then be used to calculate the system heat capacity, C, in regard to the calibration runs of the benzoic acid (Dickinson, 2015). Conclusion The amount of heat that is released from the any given sample can be calculated by observing the rise in temperature for the water as well as knowing the energy that is equivalent to the calorimeter. The results of the test are expressed in (cal/g) calories per gram. References Washburn, E. W. (2011). Standard states for bomb calorimetry. J. Res. Natl. Bur. Stand.(US), 10, 525-558. Dickinson, H. C. (2015). Combustion calorimetry and the heats of combustion of cane sugar, benzoic acid, and naphthalene (Vol. 11, No. 2). US Government Printing Office.
