A piston-cylinder device contains (0.85 kg) of refrigerant (134a) at (-10°C). The piston that is free to move has a mass of (12 kg) and a diameter of (25 cm). The local atmospheric pressure is (88 kPa). Now, heat is transferred to refrigerant (134a) until the temperature is (15°C). Determine (a) the final pressure, (b) the change in the volume of the cylinder, and (c) the change in the enthalny of the refrigerant (134a)

![Example-5:- H.W
A piston-cylinder device contains (0.85 kg) of refrigerant (134a) at (-10°C).
The piston that is free to move has a mass of (12 kg) and a diameter of (25
cm). The local atmospheric pressure is (88 kPa). Now, heat is transferred to
refrigerant (134a) until the temperature is (15°C). Determine (a) the final
pressure, (b) the change in the volume of the cylinder, and (c) the change in
the enthalpy of the refrigerant (134a).
