In this video describes the history of calorimetry and explains how it can be used to measure energy changes in a system. The specific heat of water is well established and so as a system releases or absorbs energy from a surrounding water bath it can be measured. Calorimeters can be used to measure the specific heat capacity of a substance as well as the enthalpy of fusion, vaporization, and reaction.
