-A piston of mass 60 kg sits in a cylinder containing water vapour. The diameter of the piston is 20 cm. There is a spring connected above the piston which is originally unstretched, and has a spring constant of 50 kN/m. The piston moves upwards a distance of 5 cm while 200 J of heat is added. Calculate the change in internal energy of the water vapour.
