100 kg of R-134a at 200 kPa are contained in a piston–cylinder device whose volume is 12.766 m3. The piston is now moved until the volume is one-half its original size. This is done such that the pressure of the R-134a does not change. Determine the final temperature and the change in the total internal energy of R-134a. Use data from the steam tables.

The final temperature is  °C.

The total change in internal energy is  kJ/kg.
