Chapter 9, Problem 22E

A 70.0-g piece of metal at 80.0 °C is placed in 100 g of water at 22.0 °C contained in a calorimeter like that shown in Figure 9.12. The metal and water come to the same temperature at 24.6 °C. How much heat did the metal give up to the water? What is the specific heat of the metal?

Figure 9.12 A simple calorimeter can be constructed from two polystyrene cups. A the mometer and stirrer extend through the cover into the reaction mixture.
