In the laboratory a "coffee cup" calorimeter, or constant pressure calorimeter, is frequently used to determine the specific heat of a solid, or to Thermometer measure the energy of a solution phase reaction. A stúdent heats 63.82 grams of silver to 99.27 °C and then drops it into a cup containing 83.16 grams of water at 24.20 °C. She measures the final temperature to be 27.20 °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. Water Assuming that no heat is lost to the surroundings calculate the specific heat of silver. Metal sample Specific Heat (Ag) = 1/g°C.
