A massless piston divides a closed, thermally insulated cylinder into two equal parts. One part contains M = 28 g of nitrogen. At this temperature, one -third of molecules are dissociated into atoms and the other part is evacuated. the piston A massless piston divides a closed one -third of molecules are dissociated into atoms and the other part is evacuated. the piston thermally insulated cylinder into two equal parts.
