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 63.65 grams of zinc to 98.92 °C and then drops it into a cup containing 76.71 grams of water at 22.10 °C. She measures the final temperature to be 27.79 °C. The heat capacity of the calorimeter (sometimes referred to as the calorimeter constant) was determined in a separate experiment to be 1.79 J/°C. Assuming that no heat is lost to the surroundings calculate the specific heat of zinc. Specific Heat (Zn) = J/g°C.
