Consider the piston-cylinder arrangement shown in the figure containing air. Initially the spring is totally deflected and the piston is just touching the top stops. At this point the volume inside the cylinder is 1 m and the pressure inside is 1900 kPa. The system is cooled down and heat is transferred from the system to the surroundings and the system is compressed, until the final volume is half of the initial value. At this state the pressure inside the cylinder is 900 kPa. At this point the piston touches the spring, exerting no force on it. During the process, the spring force is proportional to the displacement of the piston from its original position. Determine: Po 1. Show the process in a P-V diagram 2. Find the total work (W2)done during the process using the analytical method. 3. Find the work done by the spring, Consider the piston-cylinder arrangement shown in the figure containing air.
