2.8: Heat of a Reaction and Coffee Cup Calorimeter-Home

SOLVED: 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 lead weighing 19.69 grams and originally at 98.25 °C is dropped into an insulated cup containing 78.40 grams of water at 20.74 °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.Using
