Two small containers, each with a volume of 100cm3 , contain helium gas at 0oC and 1.00atmpressure. The two containers are joined by a small opentube of negligible volume, allowing gas to flow from onecontainer to the other. What common pressure will exist in the two containers if the temp of one container israised to 100oC while the other container is keptat 0oC?
