1) In a Piston-Cylinder system, it initially contains 2.8 bar and 40'C temperature R-134a refrigerant and the initial volume is 0.1 m3. First, heat is transferred to the system by holding the piston constant and this process is continued until the pressure is 3.2 bar. The process is then maintained by allowing the volume to change while the pressure is kept constant. At the end of this process, the temperature reaches 50'C. Assuming the process

First, heat is transferred to the system by holding the piston constant and this process is continued until the pressure is 3.2 bar. The process is then maintained by allowing the volume to change while the pressure is kept constant. At the end of this process, the temperature reaches 50'C. Assuming the process changes as balanced, calculate the following.
a) The mass of R-134a refrigerant in the system,
b) The amount of heat transferred during the fixed volume process,
c) Calculate the amount of heat transferred during constant pressure operation.
d) Show the state changes on the P-v diagram.
