In the laboratory a student determines the specific heat of a metal. he heats 19.5 grams of copper to 98.27 °c and then drops it into an insulated cup containing 76.3 grams of water at 24.05 °c. when thermal equilibrium is reached, he measures the final temperature to be 25.69 °c. assuming that all of the heat is transferred to the water, he calculates the specific heat of copper to j/g°c.
