R-134a at state 1 is contained in a piston-cylinder device at T₁ = -12°C and P₁ = 0.2MPa. The fluid is heated at constant pressure to state 2 such that V₂ = 25V₁. Heat is then added at constant volume until it reaches state 3 the temperature T3 = 80°C. a. Show the process on a T-v diagram. b. Calculate h1,h2 and h3.
