A frictionless piston-cylinder assembly is given in the figure. Use the data on the figure. Inside the piston, there is an inert (inert) incompressible gas whose properties are given in the figure. The system is initially in equilibrium and there is a linear spring touching the piston, but it does not exert a force on the piston. Then the gas is heated and in the last case the gas has a volume of 498 L, with pressure and volume changing linearly throughout the process. If the work done to the pedestrian by this gas is 89 kJ:

k linear

a. What is the final pressure in Pa?

b. What is the total work done by the gas?

c. If the spring is compressed 0.2 m in its final state, find the spring constant. If not found, explain why
