Assume you use calorimetry to calculate the specific heat capacity of a 125.24 g piece of unknown metal. You intially heat the metal to 100.0 °C in boiling water. You then drop the chunk of metal into a calorimeter containing 45.22 g of water at 21.6 °C. After closing and stiring the calorimeter thoroughly, the metal and water both come to equilibrium at a temperature of 28.3 °C. 1. What is the temperature change of the water? 6.7 °C 21.6...
