Construction and Calibration of Calorimeter A calorimeter is a device used to measure heat release or absorption in chemical reactions. A simple calorimeter can be made from common materials such as two Styrofoam cups, a lid and a thermometer. To make a calorimeter simply place one cup inside the other, cover the top of it with the lid and place the thermometer through the lid. When making the calorimeter, it is important to try and keep the hole through which the thermometer passes as small as possible to reduce the amount of heat that escapes through it. For the same reason, this calorimeter requires two cups since the second cup provides insulation and greatly reduces the heat loss through the walls of the cup. When dealing with heat loss it is important to remember that the calorimeter itself will absorb heat from the reaction. The heat capacity of the calorimeter must be determined prior to measuring any reactions so it can be taken into account when calculating the change in temperature of the reactions. A simple procedure can be followed to calculate the heat capacity of temperature of the reactions....
