Overview of topic
Calorimeters are used to determine how much heat is changed in a chemical or physical reaction. Calorimetry measures the temperature change in a process, which is proportional to the heat capacity. We can compute the amount of heat change in the process by using the formula C = q/mT. Calorimetric measurements are taken in two different ways.
i. When the volume is constant (qV)
ii. When the pressure is constant (qp)
The enthalpy change is frequently calculated using a “coffee-cup calorimeter.” The cup is partially filled with a known volume of water, and a thermometer is put through the cup’s lid such that its bulb is below the water’s surface. When a chemical reaction happens, the water absorbs the heat of the process. The quantity of heat that has been absorbed or evolved is calculated using the change in water temperature. Little heat energy escapes because the cup is composed of polystyrene foam, which is an excellent insulator. In this process, the energy change, or enthalpy change, is computed as ΔH=qp= mcpΔT
Because the volume of the completely sealed bomb calorimeter does not change, the energy changes associated with the reaction are measured at a constant volume. The system’s work done is zero because the volume remains constant. The process’s energy change, or internal energy change, is computed as follows: ΔU=qv= mcvΔT
