Calorimetry
The subfield of thermochemistry studies the energy changes that occur over the course of various chemical reactions.
We will first look at how these changes are measured and then go into quantitative descriptions of heat transfer.
Calorimetryis a term used to describe the measurement of heat transfers, usually by monitoring changes in the
temperature of an isolated system. Acalorimeteris a device used to measure temperature changes during chemical
processes. The simplest type of calorimeter is the constant-pressure device illustrated inFigure17.3.

A basic calorimeter includes the following components:
- a thermometer to measure temperature changes.
- a stirring rod to mix materials thoroughly
- an insulated lid
- an inner container
- an outer container
