A piston-cylinder device contains 01.440 kg of refrigerant-134a at -10 degrees Celsius. The piston that is free to move has a mass of 11.52 kg and a diameter of 24.5 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.
