[References] Use the References to access important values if needed for this 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. A student heats 60.94 grams of silver to 98.31 °C and then drops it into a cup containing 79.27 grams of water at 21.78 °C. She measures the final temperature to be 25.06 °C. The heat capacity of the calorimeter (sometimes referred to as the calorimeter constant) was determined in a separate experiment to be 1.69 J/°C.
