Question

a piston cylinder device with a set of stops on the top initially contains 3 kg

Answer 1

A piston-cylinder device, with a set of stops on the top, initially contains 3 kg of air at 200 kPa and 27 degrees Celcius. Heat is now transferred to the air, and the piston rises until it hits the stops, at which point the volume is twice the initial volume.
