Calorimetry Measurement of Heat Transfer

The amount of heat absorbed by a calorimeter is sometimes expressed as the heat capacity of the calorimeter, in joules per degree. The heat capacity of a calorimeter is determined by adding a known amount of heat and measuring the rise in temperature of the calorimeter and of the solution it contains. This heat capacity of a calorimeter is sometimes called its

We add 3.358 kj of heat to a calorimeter that contains 50.00 g of water. The temperature of the water and the calorimeter, originally at 22.34°C, increases to 36.74°C. Calculate the heat capacity of the calorimeter inJ/°C. The specific heat of water is 4.184J/g °C. 

We first calculate the amount of heat gained by the water in the calorimeter. The rest of the heat must have been gained by the calorimeter, so we can determine the heat capacity of the calorimeter. 

The total amount of heat added was 3.358 kJ or 3.358 X 10 J. The difference between these heat values is the amount of heat absorbed by the calorimeter.
