A 5-kg steel container is cured at 500oC. An amount of liquid water at 15oC, 100 kPa

Question:

A 5-kg steel container is cured at 500oC. An amount of liquid water at 15oC, 100 kPa is added to the container so a final uniform temperature of the steel and the water becomes 75oC. Neglect any water that might evaporate during the process and any air in the container. How much water should be added and how much entropy was generated?
