371525 A container of volume \(4{\rm{ }}{V_0}\) made of a perfectly non-conducting material is divided into two equal parts by a fixed rigid wall whose lower half is non-conducting and upper half is purely conducting. The right side of the wall is divided into equal parts (initially) by means of a massless non-conducting piston free to move as shown. Section \(A\) contains \(2\;mol\) of a gas while the section \(B\) and \(C\) contain \(1\,mol\) each of the same gas \((\gamma=1.5)\) at pressure \(P_{0}\). The heater in left part is switched on till the final pressure in section \(C\) becomes \(125 / 27 P_{0}\). Calculate: Final temperature in part \(A\) :
