A sample of metal shot of 250.0 g is heated to a temperature of around 98.0°C. It is positioned in 100.0 g of water in a brass calorimeter cup having a brass stirrer. The net mass of the cup and the stirrer is around 50.0 g. The initial temperature of the water, stirrer and calorimeter cup is around 20.0°C. The final equilibrium temperature of the system is around 30.0°C. Determine the specific heat of the metal sample? (The specific heat of brass is around 0.092 cal/g–C°.) Illustrate your work.
