Answer to Question 1

The value for the specific heat will be much greater because the temperature
difference for the water and the calorimeter cup will increase and the temperature
difference for the metal will decrease. The specific heat for the metal is determined
by dividing water and cup values by the metal values.

Answer to Question 2

5
