Question

A piston/cylinder assembly contains air at 400 degC and 150kPa. The setup is allowed to cool to the ambient temperature of 20degC. 1. Determine if the piston is resting on

the stops in the final state. 2. Determine the final pressure in the cylinder 3. Determine the specific work (work/mass) done by the air during this process. 4. Is it appropriate to use the ideal gas law during this process? Justify your answer. 5. Sketch the process on a T-v diagram 6. Sketch the process on a P-v diagram
