Steam is used to cool a polymer reaction. The steam in the steam chest of the apparatus is found to be at 250.5°C and 4000 kPa absolute during a routine measurement at the beginning of the day. At the end of the day the measurement showed that the temperature was 650°C and the pressure 10,000 kPa absolute. What was the internal energy change of 1 kg of steam in the chest during the day? [Coul you also please let me know what steam tables you utilized and how you arrived at the v, u, or H value)

 Steam is used to cool a polymer reaction. The steam in the steam chest of the 
apparatus is found to be at 250.5°C and 4000 kPa absolute during a routine measurement at 
the beginning of the day. At the end of the day the measurement showed that the 
temperature was 650°C and the pressure 10,000 kPa absolute. What was the internal 
energy change of 1 kg of steam in the chest during the day? [Coul you also please let me know what steam tables you utilized and how you arrived at the v, u, or H value)
