A piston cylinder device contains 0.3kg of R134-a initially at 0 C and 400 kPa. The cylinder is then heated until the final volume is 18L. The local atmospheric pressure is 100 kPA. The cylinder has a diameter of 0.2m.

  1. What is the initial volume of the R134-a?
  2. What is the final temperature?
  3. How much work is done during the heat transfer process?
  4. How much heat is transferred to the R134-a?
  5. What is the mass of the piston?
