Document Summary
Thermochemistry is the study of energy or heat absorbed or exerted by a system during a chemical reaction. In this experiment the energy involved in four separate experiments were determined. Venkatescaren (2014) explains in the experiment 3: enthalpy of various. Reactions , a calorimeter is a tool used to determine the energy change associated with a given reaction. In this experiment a coffee cup calorimeter is used and it is assumed that no energy is lost to the surroundings through the styrofoam cups (exp. In order to do this the temperature change in the calorimeter is monitored and recorded at time intervals to help calculate the energy change of the reaction. The first experiment involved a metal that was heated to 1000c being added to room temperature distilled water in the calorimeter. The associated water temperature change that occurred when the metal was added to the water helped to determine the specific heat capacity of the metal.
