On what principle does calorimetry depend

Web1 de fev. de 2024 · Calorimetry is used to measure amounts of heat transferred to or from a substance. To do so, the heat is exchanged with a calibrated object (calorimeter). The change in temperature of the measuring part of the calorimeter is converted into the amount of heat (since the previous calibration was used to establish its heat capacity). Web14 de fev. de 2024 · 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
