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. A chunk of zinc weighing 19.98 grams and originally at 98.18 °C is dropped into an insulated cup containing 84.14 grams of water at 23.18 °C. The heat capacity of the calorimeter (sometimes referred to as the calorimeter constant) was determined in a separate experiment to be 1.57 J/°C. Using the accepted value for the specific heat of zinc (See the References tool), calculate the final temperature of the water. Assume that no heat is lost to the surroundings. Tfinal = °C. |

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...
