QUESTION 3 a) Air is contained in a vertical piston-cylinder assembly fitted with an electrical resistor. The atmosphere exerts a pressure of 1 bar on the top of the piston, which has a mass of 45 kg and a face area of 0.09 m?. Electric current passes through the resistor, and the volume of the air slowly increases by 0.0453 m while its pressure remains constant. The mass of the air is 0.27 kg, and its specific internal energy increases by 18.9 kl/kg. The air and piston are at rest initially and finally. The piston-cylinder material is a ceramic composite and thus a good insulator. Friction between the piston and cylinder wall can be ignored, and the local acceleration of gravity is g = 9.81 m/s. Determine the heat transfer from the resistor to the air, in kl, for a system consisting of: i. the air alone (Figure 4-a), and ii. the air and the piston (Figure 4-b).
