A piston-cylinder device contains 0.05 m^3 of a gas initially at 200 kPa. At this state, a linear spring that has a spring constant of 150 kN/m is touching the piston but exerting no force on it. Now heat is transferred to the gas, causing the piston to rise and to compress the spring until the volume inside the cylinder doubles. If the cross-sectional area of the piston is 0.1 m^2, determine the total work done by the gas. It will be helpful to draw the P-V diagram to get the total work done by the gas. 28.75 kJ 22.25 kJ 20.75 kJ 15.55 kJ
