A cylinder which is in a horizontal position contains an unknown noble gas at 5.26 × 104 Pa and is sealed with a massless piston. The piston is slowly, isobarically moved inward 0.163 m which removes 1.59 × 104 J of heat from the gas. If the piston has a radius of 0.338 m, calculate the change in internal energy of the system.
