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 (Figure 1). 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 m 3 ) of the compartment A after the system attains equilibrium is

(2.22)
As in fig 2, the system attains equilibrium, so,
P A = P B and T A = T B
Due to sliding of piston vol. of A will be increased by x and that of B will be decreased by x.
V A =1+x
V B = 3-x
Hence volume of container A will be
