2- A piston cylinder shown in the Fig. below contains 0.5 m³ of R-410A at 2 MPa, 150°C. The piston mass and atmosphere gives a pressure of 450 kPa that will float the piston. The whole setup cools in a freezer maintained at -20°C. Find the heat transfer and show the P-v diagram for the process when T₂ = -20° C. 2 Po R-410A
