In a piston-cylinder assembly, 20 KJ of boundary work is being done on the piston. Assuming that there is heat loss to the surroundings and that the change in internal energy is 6 KJ, what is the amount of heat loss in KJ ? Additionally, if the culinder has a diameter of 40cm, determine the axial displacement of the piston. The pressure inside the cylinder is a constant 200KPa.
