If someone could please work this. I did the problem but am getting a different answer than what the professor did in class.
I think it starts off with the pressure incorrect. P_atm of 111kPa, and he got a value of 90.398kPa.
2. A piston-cylinder device contains 0.85 kg of refrigerant-134a at -10Â°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 15Â°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.
