In the laboratory a "coffee cap" calorimeter, or constant pressure calorimeter, is frequently used to determine the specific heat solid or to the energy of solution phase reaction Since the cup itself can absorb energy a separate experiment is needed to determine the heat capacity of the calorimeter. This is known as the calorimeter and the value determined in 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 90.33 grams of lead 97.79 degree C and then drop is it into a cup containing 79.19 grams of water at 20.89 degree C. She measures the final temperature to be 24.07 degree C. Using the accepted value for the specific heat of lead (See the References tool), calculate the calorimeter constant Calorimeter Constant.
