WebLab 8: Determining Enthalpy of Calorimetry Reactions. Introduction: The purpose of this lab is to determine the enthalpy of a chemical reaction three different ways for a company. The heat energy change of a system cannot always be measured directly, but the heat energy change of the surroundings can be found by monitoring temperature changes. WebThis evidence suggests that it takes more heat to raise the temperature of some substances than others, which is true. The amount of heat required to raise the temperature of 1 g of a substance by 1 degree is called the specific heat capacity of that substance. Water, for instance, has a specific heat capacity of 4 J/K·g. WebFormal Lab Report: Experiment 25 Calorimetry Priscilla Rangel CHEM 1411-Abstract The main purpose of the Calorimetry experiment is to measure the enthalpy, specific heat capacity, of substances using a calorimeter.
