A spring loaded piston cylinder device is initially filled with 0.1 kg of R-134a saturated liquid vapor mixture whose temperature is at -34 oC and quality is 80 percent. The spring constant in the spring force relation F=kx is 6480 N/m and the piston diameter is 0.305 m. The R-134a undergoes a process that increases its volume by 40 percent. Calculate the final temperature and enthalpy of the R-134a.

R-134a:
vf = .0007142
vg = .27090
hf = 7.566
hg = 229.65
hfg = 222.09
