2. (25 Pts) 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°C and quality is80%. The

spring constant in the spring force relation (F = kx) is 12494 N/m and the piston diameter is 0.305 m. The R-134a undergoes a process that increases its volume by 60%. Calculate the final temperature and final enthalpy of the R-134a.
