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. Thememte Siming n A student heats 62.11 grams of zinc to 98.17 °C and then drops it into a cup containing 75.89 grams of water at 23.33 °C. She measures the final temperature to be 28.77 °C. The heat capacity of the calorimeter (sometimes referred to as the calorimeter constant) was determined in a separate experiment to be 1.83 J/°C. Assuming that no heat is lost to the surroundings calculate the specific heat of zinc. Mtal Specific Heat (Zn) = [ J/g°C. Subinit Answer Retry Entire Group 8 more group atlempts remaining 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. Themuneter 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 of known heat capacity. In the laboratory a student heats 99.26 grams of zinc to 98.53 °C and then drops it into a cup containing 79.98 grams of water at 21.60 °C. She measures the final temperature to be 29.50 °C.
