A piston cylinder contains 1m3 of gas initially at 100 kPa. Consider linear spring and has a spring constant of 200 kN/m touching the piston but not exerting any force on it. Now the heat is transferred to the gas inside the cylinder. The area of the cross-section is 0.25 m2. Calculate work done by gas until the volume of the gas is double its initial volume in kJ.
