2. A 155 g sample of iron metal at 120.0C is placed into 250.0g of water at 20.0 °C in a calorimeter. When the system reachesthermal equilibrium, the temperature of the water in thecalorimeter is 30.8C. Assume the calorimeter is perfectlyinsulated. What is the specific heat of iron? What is the amount ofheat for 80.0 g piece of iron?
