A piston-cylinder device contains 0.398 kg of refrigerant-134a at -10 degrees Celsius. The piston that is free to move has a mass of6.5 kg and a diameter of 18.4 cm. The local atmospheric pressure is 88 kPa. Now, heat is transferred to refrigerant-134a until the temperature is 15 degrees Celsius. 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.
