10 kJ of heat enters a piston-cylinder. The internal energy of the piston-cylinder increases by 2 kJ. How much work is produced by the piston-cylinder?

In the previous problem, 10 kJ of heat entered a piston-cylinder. The internal energy of the piston-cylinder increased by 2 kJ. Now assume that the top of the piston is free to move and the pressure is 200 kPa. The initial volume is 0.02 m3. What is the final volume?
