Constant-volume calorimetry | Thermodynamics | AP Chemistry | Khan Academy


Constant-volume calorimetry is used to measure the change in internal vigor, DE, for a combustion action. In this technique, a test is burned under constant loudnes in a design called a bomb calorimeter. The extent of hot released in the reaction can be calculated using the equation q= -CDT, where C is the heat capacity of the calorimeter and DT is the temperature change. Because the combustion occurs at constant volume, q is equal to DE for the reaction.
