Thus, calorimetry requires the understanding of the basic thermodynamics for evaluation of the process and its heat energy. Thus, in the subsequent section, the basic thermodynamics, calorimetry process thermodynamics, principle of bomb calorimetry , Boy’s calorimeter and Junker’s calorimeter are discussed with their applications. What is Bomb Calorimeter ? The bomb calorimeter is used to determine the calorific value of solid and liquid fuels, while the gas calorimeter is used for gaseous fuels. Working Principle A measured quantity of fuel is burned in the calorimeter , and the heat released is used to heat water within the apparatus. Constant Volume Calorimetry , also know as bomb calorimetry , is used to measure the heat of a reaction while holding volume constant and resisting large amounts of pressure. Although these two aspects of bomb calorimetry make for accurate results, they also contribute to the difficulty of bomb calorimetry . In this module, the basic assembly of a bomb calorimeter will be addressed, as well as how bomb calorimetry relates to the heat of reaction and heat capacity and the calculations involved ... Learn how a bomb calorimeter measures the heat of combustion of a substance by burning it in a sealed container and absorbing the heat in water. Find out the components, formula, applications, and advantages and disadvantages of this laboratory apparatus.
