Question

A piston–cylinder device contains 0.05 m3 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 0.25 m2
, determine (a) the final pressure inside the cylinder, (b) the total work
done by the gas.
