a.
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 99.48 grams of copper to 98.85 °C and then drops it into a cup containing 85.25 grams of water at 23.84 °C. She measures the final temperature to be 31.08 °C. Using the accepted value for the specific heat of copper (See the References tool), calculate the calorimeter constant. |

A chunk of magnesium weighing
18.66 grams and originally at 97.77
°C is dropped into an insulated cup containing
78.63 grams of water at 20.31
°C.
The heat capacity of the calorimeter (sometimes referred to as the
calorimeter constant) was determined in a separate
experiment to be 1.56 J/°C.
Using the accepted value for the specific heat of
magnesium (See the References tool), calculate the
final temperature of the water. Assume that no heat is lost to the
surroundings.
