Using Energy Concepts and the Ideal Gas Model

As shown in Fig. P3.134, a rigid tank initially contains 3 kg of carbon dioxide (CO₂) at 500 kPa. The tank is connected by a valve to a piston–cylinder assembly located vertically above, initially containing 0.05 m³ of CO₂. Although the valve is closed, a slow leak allows CO₂ to flow into the cylinder from the tank until the tank pressure falls to 200 kPa. The weight of the piston and the pressure of the atmosphere maintain a constant pressure of 200 kPa in the cylinder. Owing to heat transfer, the temperature of the CO₂ throughout the tank and cylinder stays constant at 290 K. Assuming ideal gas behavior, determine for the CO₂ the work and heat transfer, each in kJ.
