Extracted text: 6. You have a block of Copper (mass: 10 kg, temp: 800 K) and water of mass 100 kg, temp: 290 K. What is the maximum amount of work obtainable from the process? Cp (in kJ/kg.K) values for water and Copper: 4.185 and 0.398 respectively. 7. Repeat the problem 6 if the same Copper block with same initial condition of temperature is dropped in a lake of temperature 280 K.
