A cylinder which is in a horizontal position contains an unknown noble gas at 4.63 × 104 Pa and is sealed with a massless piston. The piston is slowly, isobarically moved inward 0.202 m, while 1.95 × 104 J of heat is removed from the gas. If the piston has a radius of 0.283 m.
calculate the change in internal energy of the system
