Document Summary
During the process of some chemical or physical reactions heat energy is transferred which affects the temperature around it and the study of the heat change that occurs is known as calorimetry. The device which measures the change in temperature is called a calorimeter and is isolated from the external environment so the temperature of the internal environment can be found. Calorimetry uses many techniques such as titration, flow, sorption and reaction and is used to study all types of reactions. (haines, 2002). It is not a sealed system which means the internal pressure is equal to the atmospheric pressure. The pressure does not change within the system which means that the change in heat and the enthalpy change will remain the same. Two substances are placed in the calorimeter and they start to mix together and a thermometer will be placed and the temperature will be recorded after a certain amount of time.
