Chapter 15. Laboratory: Thermochemistry and Calorimetry
Thermochemistry is the study of the heat evolved or absorbed during chemical reactions, physical transformations (such as mixing), and phase changes (such as melting). Calorimetry, from the Latin words calor for heat and metrum for measure, is a technique used to measure the heat changes that occur in such processes.
All of the laboratories in this chapter require a calorimeter, a device that thermally isolates the process being investigated, preventing gain or loss of heat from the external environment. We used an inexpensive purpose-built calorimeter, which is available from Home Science Tools ...
