A closed tank has two compartments A and B, both filled with oxygen(assumed to be an 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
m3) of the compartment A after the system attains equilibrium is _________.
