3/30/2013◦ The insulated device used tomeasure the absorption or release ofheat in chemical or physicalprocesses is called a calorimeter.◦ The heat content of a system atconstant pressure is the same as aproperty called the enthalpy (H) ofthe system.◦ Constant-Volume Calorimeters• Calorimetry experiments can be performed at aconstant volume using a bomb calorimeter.12
