A piston'eylinder has two chambers and ineludes a spring, as illustrated below. The right side contains air at 318.15 K and 2 bar, while the left side is a spring in a vacuum. The spring exerts a force to the right of 5500x (SI units), where x is initially 0.3 m away from the right side of the wall (x = 0 is the position where the spring is fully relaxed). The piston has a cross-sectional area of 0.1 m?. Assume that the piston and cylinder are both well insulated. When the red stop is removed, the piston moves smoothly to a final state.
