Suppose you have two identical containers with the samevolume, both submersed in a hot water bath so that both containersare at the same temperature. One container is filled with one mol of hydrogen gas (H2) while the other holds one mole of nitrogen gas (N2). What can you conclude about thepressures in the two containers? Of course, nitrogenmolecules are more massive than hydrogen molecules. How can that difference be understood in light of your conclusion about the pressures?
