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.

Question 5 of 26 Fill in the blanks: A substance having a mass 1.5 g is burned in a bomb calorimeter. The temperature started at 20.2 °C and leveled off at 23.5 °C. The manufacturer of the bomb calorimeter determined the heat capacity of the calorimeter to be 15.3 kJ/°C. Calculate the heat of combustion per gram of the given substance. Type your answer in whole number. kJ/g Answer:
In an experiment, 26.5 g of metal was heated to 98.0°C and then quickly transferred to 150.0 g of water in a calorimeter. The initial temperature of the water was 22.5°C, and the final temperature after the addition of the metal was 32.5°C. Assume the calorimeter behaves ideally and does not absorb or release heat.
