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. Stirring rod A student heats 65.13 grams of copper to 98.95 °C and then drops it into a cup containing 84.76 grams of water at 23.02 °C. She measures the final temperature to be 27.86 °C. The heat capacity of the calorimeter (sometimes referred to as the calorimeter constant) was determined in a separate experiment to be 1.60 J/°C.

They are all one 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 60.42 grams of chromium to 98.12 °C and then drops it into a cup containing 82.86 grams of water at 23.37 °C. She measures the final temperature to be 28.57 °C.The heat capacity of the calorimeter (sometimes referred to as the calorimeter constant) was determined in a separate experiment to be 1.80 J/°C.Assuming that no heat is lost to the surroundings calculate the specific heat of chromium.Specific Heat (Cr) = ______J/g°C. 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.Since the cup itself can absorb energy, a separate experiment is needed to determine the heat capacity of the calorimeter. This is…
