Question: A 0 . 4 0 m 3 0 . 4 0 - m 3 insulated piston - cylinder device initially contains 1 . 3 kg

A 0.40m30.40-m3 insulated piston-cylinder device initially contains 1.3 kg of air at 30C. At this state, the piston is free to move. Now air at 500 kPa and 70C is allowed to enter the cylinder from a supply line until the volume increases by 50 percent. Use data from tables. Use constant specific heats at room temperature.
Determine the work done. Determine the final temperature. Determine the amount of mass that has entered. Determine the entropy generated.
