Question

Raview Toplcs) Use the References to access ispertant values if needed for this 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. 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 constanr One way to do this is to use a common metal of known heat capacity. In the laboratory a student heats 95.47 grams of copper to 98.99°C and then drops it into a cup containing 79.09 grams of water at 21.46 °C. She measures the final temperature to be 29.18 C Using the accepted value for the specific heat of copper (See the References tool), calculate the calorimeter constant Calorimeter Constantc Submit Answer Retry Entire Group 8 more group attempts remaining Previous Next 8 0.
