A student heats 61.30 grams of lead to 98.08 °C and then drops it into a cup containing 82.53 grams of water at 22.76 °C. She measures the final temperature to be 24.74 °C. The heat capacity of the calorimeter (sometimes referred to as the calorimeter constant) was determined in a separate experiment to be 1.88 °C. Assuming that no heat is lost to the surroundings calculate the specific heat of lead. Specific Heat (Ph) =
