Acylinder 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 0.163 m, while 1.95 × 104 j of heat is removed from the gas. if the piston has a radius of 0.272 m, calculate the change in internal energy of the system.
