A blacksmith heats a copper work-piece to 800°C and then quenches it using water.The work-piece has a mass of 5.0 kg and has been immersed in a vessel containing 200 L of water at initial temperature of 20°C. Assume the vessel is perfectly insulated, and the specific heat of copper and water are 0.385 kJ kg–1K–1 and 4.18 kJ kg–1K–1 respectively. (a) Calculate the final temperature of the copper work-piece.  (b) Calculate the change in internal energy of the work-piece between the initial and final states.
