A closed tank has two compartments A and B, both filled with oxygen (assumed to be ideal gas). The partition separating the two compartments is fixed and is a perfect heat insulator (Figure1). If the old partition is replaced by a new partition which can slide and conduct heat but does not allow the gas to leak across (Figure 2), the volume (in m3) of the compartment A after the system attains equilibrium is _________.

Solution

When equilibrium is established, the final T and P would be the same. Hence, volume ration would be equal to mole ratio. v1v2=n1n2 v1v2=5400R3300R=54  v1vT=59  v1=59×vT=59×4 =2.22
