Question

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 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 72 grams of copper to 98 82 C and then drops it into a cup containing 77 51 grams of water at 22 98 C She measures the final temperature to be 30 32 C Using the accepted value for the specific heat of copper See the References tool calculate the calorimeter constant Calorimeter Constant 11 C
