Consider a case where gas A and gas B are kept at the same temperature and both have the same mass. The attractive forces between molecules gas A are appreciable at a moderately high pressure and the repulsive forces are predominant at very high pressure. On the other hand, the intermolecular forces are virtually nil among molecules gas B. Sketch the graph PV/RT versus P for these two gases.
