In a piston cylinder assembly 20kj of boundary work is being done on the piston assuming there is heatloss to the surroundings and that change in internal energy is 6 kj what is the amount of heat loss in kj additionally if the cylinder has a diameter of 40 cm determine the axial displacement of the piston the pressure inside the piston is a constant 200kpa and the change in internal energy for the process is plus 12kj

i mean i gues
