In the laboratory a student uses a "coffee cup" calorimeter to determine the specific heat of a metal. She heats 18.0 grams of lead to 97.76°C and then drops it into a cup containing 82.5 grams of water at 21.01°C. She measures the final temperature to be 21.62°C. Assuming that all of the heat is transferred to the water, she calculates the specific heat of lead to be J/g °C.
