A mass less piston divides a closed thermally insulated cylinder into two equal parts One part contains m 28 gram of nitrogen at temperature To At this temperature one third of molecules are dissociated into atoms and the other pa is evacuated The piston is released and the gas fills the whole volume of the cylinder Then the piston is slowly displaced back to its initial position The increase in internal energy of the gas is Neglect further dissociation of molecules during motion of the piston A 2 1 RTO C 2 1 RTO B 2 1 RTO D 2 1 RTO
