A 1-kg copper block at the initial temperature of 527 degrees C has been placed inside a perfectly insulated vessel containing 10 kg of water at the initial temperature of 27degrees C. The final temperature of the copper block is measured after the system has reached equilibrium. Assume the specific heat of copper equal to 0.38 kJ kg-1K-1.
a) Calculate the final temperature of the copper block.
b) Calculate the change in internal energy of the copper block between the initial and final states.
