Calorimetry

Mr. Anderson explains calorimetry, a method to measure heat, tracing its origins to Antoine Lavoisier's ice calorimeter. He describes the basic components of a calorimeter, including a heat bath and a chemical system, and explains how it measures energy changes. The video covers specific heat calculations using water as an example and discusses the bomb calorimeter's role in measuring enthalpy and energy changes in chemical reactions.
