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.
Themuneter
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 99.26 grams of zinc to 98.53 °C and then drops it into a
cup containing 79.98 grams of water at 21.60 °C. She measures the final temperature to be 29.50 °C.
Metul
Using the accepted value for the specific heat of zinc (See the References tool), calculate the calorimeter constant.
Calorimeter Constant =
J/°C.
