3–38 100 kg of R-134a at 200 kPa are contained in a piston-cylinder device whose volume is 12.322 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 cotal internal energy of the R-134a.

Question
3-38 100 kg of R-134a at 200 kPa are contained in a
piston-cylinder device whose volume is 12.322 m²³. 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 the R-134a.
