Calorimetry. Calorimetery is an application of the First Law of Thermodynamics to heat transfer, and allows us to measure the enthalpies of reaction or the heat capacities of substances. From the first law we can state. ΔEUniverse = ΔESystem + ΔESurrounding = 0. therefore, ΔESystem = − ΔESurrounding.
