In the laboratory a "coffee cup" calorimeter, or constant pressure calorimeter, is frequently used to determine the specific heat of a solid, or to measure the energy of a solution phase reaction. Thermometer Stirring rod Since the cup itself can absorb energy, a separate experiment is needed to determine the heat capacity of the calorimeter. This is known as calibrating the calorimeter and the value determined is called the calorimeter constant. One way to do this is to use a common metal of known heat capacity. In the laboratory a student heats 90.16 grams of nickel to 98.98 °C and then drops it into a cup containing 84.90 grams of water at 22.80 °C. She measures the final temperature to be 30.48 °C. Water Metal sample Using the accepted value for the specific heat of nickel (See the References tool), calculate the calorimeter constant. e2003 ThomeonrkCoe Calorimeter Constant = J/°C.
