Answer to Question #67098 in Other Engineering for H
A piston-cylinder device contains 1.38 kg of refrigerant-134a at -10 oC. The piston that is free to move has a mass of 16 kg and a diameter of 11.18 cm. The local atmospheric pressure is 84 kPa. Now, heat is transferred to refrigerant-134a until the temperature is 90 oC. Determine (a) the final pressure (kPa), (b) the change in the volume of the cylinder (m3), and (c) the change in the enthalpy of the refrigerant-134a (kJ/g). Submit your answer by mutiplying the answers (a)*(b)*(c) = _______.
