A metal sample weighing 34.526 g was heated to 98.0 C then quickly transferred into Styrofoam cup calorimeter containing 74.365 g of distilled water at a temperature of 27 C. The temperature of the water in the cup increased and stabilized at 29 C.

1. What is the final temperature of both the water and the metal?
2. Calculate the change in temperature of the water in the calorimeter.
3. Calculate the change in temperature of the metal.
4. Calculate the heat gained by the water.
5. What is the heat lost by the metal sample?
6. Calculate the specific heat of the metal?
7 What is the metal?
