Consider a vertical piston-cylinder assembly with a 50 kg piston attached to a spring and exposed to atmospheric pressure of 100 kPa. The piston has a surface area of 250 cm^2 and the local acceleration of gravity is 9.81 m/s^2. Heat is now transferred to the system causing it to expand until the volume is 50% greater than the initial volume and reaches 0.003m^3, at which the state pressure in the cylinder is 2 bar. During the process, the spring exerts a force that varies linearly from an initial value of 0 N to a final value. Neglect friction between the piston and the cylinder.
Considering air inside the cylinder as the system, calculate the work done by the system and the percentage of the work done against the spring.
