Average Specific Heat Capacity of the Unknown Metal:

Post-Lab Questions

1. Why is ?T_metal < 0?
2. Why is ?T_water > 0 ?
3. A metal sample weighing 43.5 g and at a temperature of 100.0 °Cwas placed in 39.9 g of water in a calorimeter at 25.1 °C. Atequilibrium the temperature of the water and metal was 33.5 °C.Determine the specific heat capacity of the metal.
4. What is the average specific heat capacity of the unknown metalin this experiment?

What is the unknown metal? Use Table 1 for reference.
